Switch statement work with byte,short,int,long, enum types, String and some wrapper type like Byte, Short, Int, and Long. the switch statement tests the equality of a variable against multiple values. Duplicate case values are not allowed. The value for a case must be of the same data type as the variable in the switch. The value for a case must be a constant or a literal. Variables are not allowed. class Main {     public static void main(String args[]) {         byte by=10;         switch((byte)(by+118)) {             default:System.out.println("Sunday");             case (byte)0:System.out.println("Monday");             case (byte)128:System.out.println("Thank u");         }     } }
