switch type in java code example

Example 1: java switch

int day = 4;
switch (day) {
  case 6:
    System.out.println("Today is Saturday");
    break;
  case 7:
    System.out.println("Today is Sunday");
    break;
  default:
    System.out.println("Looking forward to the Weekend");
}
// Outputs "Looking forward to the Weekend"

Example 2: java switch on what classes

A switch works with the byte, short, char, and int primitive data types.
It also works with enumerated types (discussed in Enum Types), the String
class, and a few special classes that wrap certain primitive types: 
Character , Byte , Short , and Integer (discussed in Numbers and Strings).
