Why character array is better than String for Storing password in Java? Example

Why character array is better than String for storing a password in Java was a recent question asked to one of my friends in a java interview. he was interviewing for a Technical lead position and has over 6 years of experience. Both Character array and String can be used to store text data but choosing one over the other is a difficult question if you haven't faced the situation already. But as my friend said any question related to String must have a clue on a special property of Strings like immutability and he used that to convince the interviewer. here we will explore some reasons why should you use char[] for storing passwords than String.

Difference between Stack and Heap memory in Java? Example

The difference between stack and heap memory is a common programming question asked by beginners learning Java or any other programming language. Stack and heap memory are two terms programmers start hearing once they started programming but without any clear and definite explanation. Lack of knowledge of what is a heap in Java and what is stack memory in Java results in misconceptions related to stack and heap. To add to this confusion, a stack is also a data structure that is used to store elements in LIFO(Last In First Out) order and is available in Java API as java.util.Stack.

What is load-on-startup servlet element in web.xml with Example?

load-on-startup is an element that appears inside <servlet> tag in web.xml.4 years back load-on-startup was a very popular servlet interview question because not many Java J2EE developer was familiar with this element and how load-on-startup works inside a servlet container like tomcat or WebSphere. In this J2EE Tutorial, we will see what is a load on startup, how to use the load-on-startup element, and what are different values we can configure for load-On-Startup inside web.xml.

Difference between SendRedirect() and Forward() in JSP Servlet? Example

Before examining the difference between forward and SendRedirect let’s see what send Redirect method and the forward method does.

SendRedirect ():  

This method is declared in HttpServletResponse Interface.

Signature: void sendRedirect(String url)

Difference between throw and throws in Exception handling - Java Example

Difference between throw and throws keyword on Exception handling in Java is a popular core java interview question. Exception handling being an important part of Java programming language, complete knowledge of all keywords related to exception handling e.g. try, catch, finally, throw and throws is important. Main difference between throw and throws is in there usage and functionality. where throws is used in method signature to declare Exception possibly thrown by any method, throw is actually used to throw Exception in Java code, here is an example of both throw and throws keyword which makes it easy to understand difference between them.

Difference between Struts 1 and Struts 2 Web Development Framework

I had worked previously on Struts 1 but never touched Struts 2, especially since Spring MVC was there to take the leading role. Recently one of my friends ask me to help with Struts2, which leads me to look on the Struts2 framework from start. First thing I wanted to find out differences between Struts 1 and Struts 2 framework, because in my experience, if you have worked in the previous version looking differences between two versions of Struts can quickly help to find, what changes and What are the new features, concepts and improvement is offered by Struts 2. Also the difference between Struts 1 and Struts 2 is a good candidate to include in my list of Struts interview questions for quick revision.

10 points on finalize method in Java – Tutorial Example

finalize method in java is a special method much like the main method in java. finalize() is called before the Garbage collector reclaims the Object, its last chance for any object to perform cleanup activity i.e. releasing any system resources held, closing the connection if open etc. The main issue with finalize() method in Java is it's not guaranteed by JLS that it will be called by Garbage collector or exactly when it will be called, for example, an object may wait indefinitely after becoming eligible for garbage collection and before its finalize() method gets called. similarly even after finalize gets called it's not guaranteed it will be immediately collected.

What is Static and Dynamic binding in Java with Example

Static and dynamic binding in Java is two important concepts that Java programmer should be aware of. this is directly related to the execution of code. If you have more than one method of the same name (method overriding) or two variables of the same name in the same class hierarchy it gets tricky to find out which one is used during runtime as a result of their reference in code. This problem is resolved using static and dynamic binding in Java. For those who are not familiar with the binding operation, its process is used to a link which method or variable to be called as a result of their reference in code.

3 Examples to Concatenate String in Java

String concatenation is the process of joining two or more small String to create a big String. For example, you can create a full name by concatenating first and last name of a person. Java provides multiple ways to concatenate String, but the easiest of them is by using + operator. It is one of the magical operators in Java, though Java doesn't support operator overloading, it has made an exception in the case of String and + operators.  Plus operator is a binary operator and primarily used to add two numbers if both operands are integer but it can also used to concatenate String if either both or first operand is String. For example, "Java" + "Programming" will produce "JavaProgramming".

3 Ways to Convert an Array to ArrayList in Java? Example

How to convert an Array to ArrayList in Java
Have you encountered any situation where you quickly wanted to convert your array to ArrayList or ArrayList to array in Java? I have faced many such situations that motivate me to write these quick Java tips about converting an array to ArrayList and ArrayList to array in Java. Both array and ArrayList are quite common and every Java developer is familiar with this. Former is used to store objects and primitive types while later can only hold objects. The array is part of standard Java fundamental data structure while ArrayList is part of the collection framework in Java.

How to Replace Line Breaks , New Lines From String in Java - Windows, Mac or Linux Example

We often need to replace line terminator characters, also known as line breaks e.g. new line \n and carriage return \r with different characters. One of the common case is to replace all line breaks with empty space in order to concatenate multiple lines into one long line of String. In order to replace line breaks, you must know line terminator or new line characters for that platform. For example, In Windows operating system e.g. Windows 7 and 8, lines are terminated by \n\r  also known as CR+LF, while in Unix environment e.g. Linux or Solaris line terminator is \n, known as line feed LF. You can also get line terminator pragmatically by using Java system property line.terminator.

How to Convert Byte Array to InputStream and OutputStream in Java? Example

Are you stuck with your coding because you have a byte array and the next method in the chain needs an InputStream? don't worry Java has a solution for that, You can use ByteArrayInputStream to convert byte array to InputStream in Java. This class takes a byte array as the source and since it's a subclass of InputStream, you can easily pass this to any method, which accepts InputStream as a parameter. Though most of the API like JDBC and File API allows you to read directly from InputStream because this allows you to process an arbitrary content with limited heap space. You should take advantage of this and directly read from InputStream instead of getting byte array and then converting them back to InputStream.

How to Convert InputStream to Byte Array in Java - 2 Examples

Sometimes we need to convert InputStream to byte array in Java, or you can say reading InputStream as a byte array, In order to pass output to a method that accepts byte array rather than InputStream. One popular example of this, I have seen is an older version of Apache commons-codec, while converting byte array to the hex string. Though, a later version of the same library does provide an overloaded method, to accept InputStream. Java File API provides excellent support to read files like image, text as InputStream in Java program, but as I said, sometimes you need String or byte array, instead of InputStream .

How to Reverse Array in Place in Java? Solution With Explanation

Reversing an array sounds pretty easy, isn't it? It does sound like that, because all you need to do is create an array of the same size, iterate through the original array from end to start, and populate your new array. Boom!!, you have got an array that has elements in reverse order of the original array, but the problem is you have used an additional array here, which makes space complexity of your solution O(n). You cannot use this solution if the array is big e.g. an array of 10 million orders and you don't have enough heap space available.

How to Convert List of Integers to Int Array in Java - Example

So, you have a List of Integers and you want to convert them into int array? Yes, you read it write, not on Integer array but int array. Though in most practical purpose, Integer array can be used in place of int[] because of autoboxing in Java, you still need an int[] if your method accepts it. In Java, you can not typecast an Integer array into an int array. Many Java programmer think about toArray() method from java.util.List to convert a List into Array, but unfortunately, toArray() is useless most of the time. It doesn't allow you to convert List into primitive arrays.

How to Generate MD5 Hash in Java - String Byte Array Digest Example

There are multiple ways to generate the MD5 hash in Java program. Not only Java API provides a convenient method for generating MD5 hash, you can also use popular open-source frameworks like Spring and Apache commons Codec to generate MD5 digest in Java. MD5 is a popular Message-Digest Algorithm, which is most commonly used to check data integrity e.g. comparing MD5 checksum to see, if any file is altered or not. Though MD5 has not considered a good cryptographic algorithm for security purposes due to several vulnerabilities found on it, it's still good enough or checking the integrity of the file. MD5 hashing algorithm generates a 128 bit or 16-byte long hash value.

Google Protocol Buffers (ProtoBuf) - Best Alternative to Java Serialization

If you have done some serialization works in Java, then you know that it's not that easy. Since the default serialization mechanism is not efficient and has a host of problems, see Effective Java Item 74 to 78, it's really not a good choice to persist Java object in production. Though many of the efficiency shortcomings of default Serialization can be mitigated by using a custom serialized format, they have their own encoding and parsing overhead. Google protocol buffers, popularly known as protobuf is an alternate and faster way to serialize Java objects. It's probably the best alternative to Java serialization and useful for both data storage and data transfer over the network.

10 Programming Best Practices to Name Variables, Methods and Class in Java - Examples

What's in a name? "A rose by any other name would smell as sweet" is a famous quote from William Shakespeare's classic Romeo and Juliet, but sorry to say, name matter a lot in programming and coding.  It's also said that code is the best document for any software because any other document or comments can become outdated quickly, but code will always tell you the truth. And, If code is the best document then names are the most critical element of it. Every effort, small or big, invested while naming variables or methods, pays in both the short term and long term. In fact, if you ask me just one coding practice to follow, I would definitely recommend giving meaningful names to your variables and methods.

10 Tips to Learn a New Project or Codebase Quickly

One of the main drawbacks of changing a job or changing a project is that you lost all subject matter expertise you have learned by working the last couple of years in that project or domain.

Difference between Inheritance and Composition in Java and Object Oriented Programming

Though both Inheritance and Composition provide code reusability, the main difference between Composition and Inheritance in Java is that Composition allows reuse of code without extending it but for Inheritance, you must extend the class for any reuse of code or functionality. Another difference that comes from this fact is that by using Composition you can reuse code for even the final class which is not extensible but Inheritance cannot reuse code in such cases. Also by using Composition, you can reuse code from many classes as they are declared as just a member variable, but with Inheritance, you can reuse code from just one class because in Java you can only extend one class because multiple Inheritance is not supported in Java.

Why Static Code Analysis is Important? Pros and Cons

In the last few years, Software code quality and security have gone from being a “nice to have” to a necessity, and many organizations, including investment banks, are making it mandatory to pass static code analysis tests, penetration testing, and security testing before you deploy your code in production. Static analysis tools like findbugs and fortify are getting popular every passing day and more and more companies are making fortify scan mandatory for all new development.  For those unaware of what static code analysis is, static code analysis is about analyzing your source code without executing them to find potential vulnerabilities, bugs, and security threats.

Top 10 Excuses Programmers Gives to Avoid Unit Testing

Though everyone loves unit tests and everyone agrees with the benefits they bring in, when the time comes to write them, you will see a lot of excuses, even from some of the more experienced and senior developers. At the heart of the problem of not writing unit tests or enough unit tests are two things, first is time pressure i.e. you don't have enough time to complete coding forget about writing unit tests. This problem comes due to erroneous estimation i.e. only estimating time for coding and not including unit testing as part of development.
