Q&A for How to Program in Java

It really depends on how interested you are and how much time you spend learning. It also depends on if you have a programming background. There are many courses you can take online or at local colleges.

You need to create a class and define a variable. If you are using Eclipse IDE, then right click and select 'generate setter and getter,' and it will be generated.

There is only one compiler for java and that comes along with Java JDK. What you see as various compilers are actually different IDEs for java programming, so as to ease the programmer according to their own needs.

Java is basically a programming language. You have to first install Java from Oracle. Then you can use Notepad or Notepad++ as the IDE (on which to work with it). Just make sure that you save your Java file with an extension of .java.
