How can I create a Global variable in Java?

Question

Iam a java beginner and still learning the basics but get stuck with the scope of variable.

Answer 1

Java doesn't technically support global variables. As a pure object-oriented language, everything needs to be part of a class. The reason is to protect data and members of classes from being changed (inadvertently or on purpose) by other parts of the program. However, you still may need to have variables that can be accessed across your program, and not confined to specific classes.
To define Global Variable you can make use of static Keyword

public class Example { public static int a; public static int b; }

now you can access a and b from anywhere by calling

Example.a;
Example.b;
