Hi muhammad,
In C language, among others, you can define a global variable. That means that it could be used anywhere in the program without having to declare it in every method.
In java, a static variable can be used by any method in the class. It can be thought of as a global class variable. Instead of creating many local variables and passing them around as method parameters, a static class variable can be used instead.
