Java Interview Questions - Which Ones Are Most Common?

Java is one of the languages being used for web development. Before you apply for a job in a big company, you should first learn about Java Interview Questions. Java is a general purpose programming language that can be used for writing servers, web applications, desktop applications and other system programs. Some of the questions include the following:" Explain what a method is", "What is an overloading operator" and "In Java what is the difference between a pointer and a reference?". As you may guess, all these questions are related to Java and the subject matter of an interview. However there are many other programming languages that are also being used.

Some of the basic Java interview questions and answers may include: "In Java, how is the get a reference to another location?" "In Java what kind of garbage collector do you use?" "In Java how would you determine the start of the program?" These are just some basic questions and the real interview will ask you much more questions.

To prepare for your Java Interview Questions, make sure you know the basic information about Java. There are several books that are written about Java and answer all the Java Interview Questions. If you want to be prepared for the interview then you should read at least one book about Java. If you know the basic information then it will not be as difficult for you to answer the interview questions. You may also want to read more about the history of Java and find out about some of the current Java topics. You may find out things that you do not know about Java.

One of the most important aspects of answering the Java basic interview questions is thread safety. Java was created by Sun Microsystems and has a very well known and reliable model called the Servlet. In fact Java programming no matter how simple it is actually performs better with the use of the Servlet rather than the Java engine. This is because the Servlet allows the programmers to create reusable modules without having to create them again.

Another area where you will find a lot of Java Interview Questions is about the various methods overloading in the language. Almost every program that is written in Java uses a form of overloading. One of the questions you may be asked is whether or not you feel that the overloading of methods in Java makes the language harder to understand or simpler. Both arguments have strong arguments and the answer may vary depending on which perspective you choose to look at it from.

Overloading is something that is necessary when creating a more complex program. However when you are working with an existing program that uses a class instead of a derive class, overloading will not have a negative effect. Java does allow one to override static methods and it is possible to convert a static base class into a dynamic one, but this will require additional work. Therefore in general Java interview questions will ask you to consider which type of programming is easier for you to master. Overloading in Java is necessary only when dealing with derived classes where it makes sense to have the derived class is the overriding member.
