Hints

== compares whether two references point to the same object, not the text.

Solution explanation

Strings read from input are new objects, so == can be false even for equal text. equals compares the characters.

import java.util.Scanner;

public class Main {
    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);
        String a = sc.next();
        String b = sc.next();
        if (a.equals(b)) {
            System.out.println("same");
        } else if (a.equalsIgnoreCase(b)) {
            System.out.println("same ignoring case");
        } else {
            System.out.println("different");
        }
    }
