The switch statement tests the equality of a variable against multiple values.
- The case values must be unique.
- There can be n numbers of cases.
- The value must be literal or constant.
- The case value has a default label which is optional.
Syntax:
switch(expression)
{
case value1:
//code to be executed;
break;
case value2:
//code to be executed;
break;
……
default:
//code to be executed if the cases are not matched
}
class Switch1
{
public static void main(String args[])
{
int a=2;
switch(a)
{
case 1:
System.out.println("Addition program is executed");
break;
case 2:
System.out.println("Subtraction program is executed");
break;
case 3:
System.out.println("Divide program is executed");
break;
default:
System.out.println("Wrong case pressed");
}
}
}
Output:
Subtraction program is executed
