summary case can be a constant value or a final type. Then look at the following program section:public class Testswitch {public static void main (string[] args) { byte a = one; Switch (a) {//C case 11:system.out.println ("11"); break; Case 225:system.out.println ("11"); break;//D }}}Is the code correct? The answer is in the negative. Although it is legal in C, that is, a value of byte can appear in switch
