publicstaticvoid main(String[] args) {

Scanner input = newScanner(System.in);// create Scanner object System.out.println("number:");

intg= input.nextInt(); // Declare and read

switch(g==);

case1 :System.out.println("case1"); break;

case2 :System.out.println("case2"); break;

default :System.out.println("default"); }

}

2-

charg= 'a'; switch(g)

{

Case r :System.out.println("case1");

break;

case u: System.out.println("case2"); break;

default :System.out.println("default"); }
