To learn Java or any other programming language, the only best way is to practice and practice more. The more you do the coding, the better you get as time passes. These listed Java examples cover some very basic Java fundamentals and present you few alternative solutions to any single ...
Collections in Java provide far more flexibility and utilities, such as ArrayList or HashSet. For example, ArrayList offers dynamic resizing and many utility methods, and is easier to work with, especially with generics. Let’s take a look at this through some code examples: Arrays We’ve cre...
The Continue Statement in Java is used to continue loop. It is widely used inside loops. Whenever the continue statement is encountered inside a loop, control immediately jumps to the beginning of the loop for next iteration by skipping the execution of statements inside the body of loop for t...
Catch Late– Since java enforces to either handle the checked exception or to declare it in method signature, sometimes developers tend to catch the exception and log the error. But this practice is harmful because the caller program doesn’t get any notification for the exception. We shoul...

Errors and Exceptions are the subclasses of Throwable. However it hold different context for any Java program. Errors result from failures detected by the Java Virtual Machine, such as OutOfMemoryError, StackOverflowError, etc... Most simple programs do not try to handle errors. For errors progra...
The@XmlRootElementannotation uses the class name as the default element name. You can change the default name by using the annotation attributename. If you do, the specified name is used as the element name and the type name. It is common schema practice for the element and type names to...
To help make all of this more concrete I'll use a running example to talk about all of this. Like all of my examples it's one of those super-simple examples; small enough to be unreal, but hopefully enough for you to visualize what's going on without falling into the bog of a rea...
Parameters You've already seen examples of parameters, both in the Bicycle class and in the main method of the "Hello World!" application. Recall that the signature for the main method is public static void main(String[] args). Here, the args variable is the parameter to this method. The...
Also note that all the variables used in these FORTRAN examples are floating-point, except for the integer I. FORTRAN is a well-established language with a large base of support. However, newer programming languages, such as Pascal, C, and C++, have superseded it in popularity, especially ...
