why this code is not printing ( kindly choose ) help pls

Question

import java.util.Scanner;
public class program{
public static void main (String[]args){

Scanner nnur = new Scanner(System.in);
String j = nnur.nextLine();

if ( j == "yes")
{
System.out.println("kindly choose");
}
else {
System.out.println("Hi");
}
}}

Answer 1

if(j.equals ("yes"))
{}

//for ignoring capital and small letters ie... Yes & yes ... u can use ignore case ... see david's answer

Answer 2

replace if (j=="hi") with the below one, always use equalsIgnoreCase() when comparing strings.

if (j.equalsIgnoreCase("hi"));

Answer 3
