There are many programming languages available and each of them is suitable for another program or application. There are people who have learnt only a few programming languages and who use these because that is what they know, bust most of the times software programmers will use the programming language that is required by the application they are creating. Java is one of the most frequently used programming language and writing in this language is somehow different from the usual Pascal or any C/C++ version but that does not mean that learning the java code is harder than learning Pascal.
