Java programming.

What is scope? Explain the concept and use a class definition along with methods as an example to illustrate the concept. Be sure to include a discussion of static methods.

Solution

Scope of a variable means the part(s) of the program where that variable is accessible.

Example:

class Temp{
   private int a;
   public int b;
   void f(){
       int c;
   }
}

variable a:
Can be used anywhere inside the class Temp, so its scope is Temp,

variable b:
Can be used anywhere (inside the class Temp or outside it, so its scope is global).

variable c:
Can be used anywhere inside the function f, so its scope is only the function f
