Answer 1

its coming as variable a might not have been initialized so i took a from user........

import java.util.Scanner;

class SWITCH22

{

public static void main(String[] args)

{

Scanner sc = new Scanner(System.in);

System.out.println("enter a:");

int a = sc.nextInt();

int b=10;

switch(a){

case 100:

b+=5 ;

System.out.print(b) ;

break;

default:

b=b*a ;

System.out.print(b);

}

}

}
