Core Java Example
SWITCH:
Passing deferent data types
In This Example we are passing various data types into switch .In this
example we are passing int ,short, long values. As we can see at compile time it
will throw error. You can remove comments and check it.
SOURCE CODE
public class SwitchExample1{
static short sh;
static int num;
static long l;
public SwitchExample1(){
switch(sh)
{
case 0: System.out.println(sh);
break;
case 1: System.out.println(sh);
break;
case 2: System.out.println(sh);
break;
case 3: System.out.println(sh);
break;
default:
System.out.println("Default");
break;
}
switch(num)
{
case 0: System.out.println(num);
break;
case 1: System.out.println(num);
break;
case 2: System.out.println(num);
break;
case 3: System.out.println(num);
break;
case 4: System.out.println(num);
break;
default:
System.out.println("Default");
break;
}
/*switch(l)
{
case 0: System.out.println(i);
break;
case 1: System.out.println(i);
break;
case 2: System.out.println(i);
break;
case 3: System.out.println(i);
break;
case 4: System.out.println(i);
break;
default:
System.out.println("Default");
break;
}
