I have a homework to implement a simple testing application, below is my current code:
import java.util.*;
public class Test{
private static int typing;
public static void main(String argv[]){
Scanner sc = new Scanner(System.in);
System.out.println("Testing starts");
while(sc.hasNextInt()){
typing = sc.nextInt();
switch(typing){
case 0:
break; //Here I want to break the while loop
case 1:
System.out.println("You choosed 1");
break;
case 2:
System.out.println("You choosed 2");
break;
default:
System.out.println("No such choice");
}
}
System.out.println("Test is done");
}
}
What I want to do now is that when 0
is pressed, it means that the user wants to quit the test, then I break the while loop
and print Test is done
, but it doesn't work like that, I know the reason might be that the "break"
breaks the switch
, how can I let it break the while loop
instead?
You can label
your while loop, and break
the labeled loop
, which should be like this:
loop: while(sc.hasNextInt()){
typing = sc.nextInt();
switch(typing){
case 0:
break loop;
case 1:
System.out.println("You choosed 1");
break;
case 2:
System.out.println("You choosed 2");
break;
default:
System.out.println("No such choice");
}
}
And the label
can be any word you want, for example "loop1"
.
