SWITCH CASE 

switch (exp)
{
 case constant 1;
          statement;
         break;
  case constant 2;
           statement;
           break;
_____________
           ________
          ________
          default;
        statement;
}

RULES FOR SWITCH CASE :=

1.)  CASE CONSTANTS MUST BE OF TYPE INT OR CHAR.

2.) NO TWO CASE MAY BE SAME.

3.) BREAK IS OPTIMAL.

4.) DEFAULT IS OPTIMAL.


EXAMPLE


class color 
{
 public static void main (string args[])
 {
  char ch = args[0.].char At(0);

  switch(ch)
   {
     case "R":
     system.out.println("RED");
     break;
     case "G":
     system.out.println("GREEN");
     break;
     case "B":
     system.out.println("BLUE");
     break;
    default;
     system.out.println("UNDEFINED"); 
   } 
  }
 }


AS SAME WE CAN MAKE A CALCULATOR OR MORE OTHER PROGRAMS.
