Thread: Simple Question: How do I input an exit code into my program?

I just want to know how I can get my program to end when the user inputs "0." By using: System.exit(0);

import java.util.Scanner; 
 
public class TestCode
{    
    public static void main (String [ ]args )
    {
        Scanner console =new Scanner(System.in); 
        System.out.println("To exit program input 0");   
        for (int y = 1; y < 11; y++ ){ // Executes output 10 times 
 
 
        System.out.println("Enter the year please:");     
        int year = console.nextInt(); 
 
 
        if (year >= 1900) {
        boolean answer = isLeapYear (year);
            if(answer) {      
 
       System.out.println("The given year is a leap year"); } 
           else { 
       System.out.println("The given year is not a leap year"); }  }
           else {       
       System.out.println("Value is invalid! Number is less than 1900.");     
   }           
  }
 }         
    public static boolean isLeapYear(int y) //y = year
     {
        if ((y % 400 == 0) || ((y % 4 == 0) && (y % 100 != 0))) // Algorithim used for calculating leap years.
        {
               return true;
        } else {
               return false;
       }    
   }
}

Any help is appreciated, thank you for your time .

You already check the input, just add another check.

That solved it, thanks a bunch.
