User can enter any number any times but user input 0 program will be terminated

Question

java code

Answer 1

You could also do:

import java.util.Scanner;

public class Program
{
public static void main(String[] args) {
Scanner sc = new Scanner(System.in);

int num = sc.nextInt();

while(num != 0) {
num = sc.nextInt();
}
}
}

Or:

import java.util.Scanner;

public class Program
{
public static void main(String[] args) {
Scanner sc = new Scanner(System.in);

while(true) {
int num = sc.nextInt();
if(num == 0) {
break;
}
}

}
}

@luka FYI there is usually no need to import java.lang as it is implicitly imported in Java programs anyhow. This is why you can use System.out.println() without an import.

Answer 2

@luka true, lol, but it will exit by default if it is the last part of the code before the end of main. Just a technicality i guess.
