%d displays question mark ? instead of number

Question

When I use %d it displays question mark ? instead of number

import java.util.Scanner;
public class Comparison {
  public static void main(String[] args) {
    Scanner input = new Scanner(System.in);
    int x;
    int y;
    System.out.println("Value of x");
    x = input.nextInt();
    System.out.println("value of y");
    y = input.nextInt();
    if (x == y)
      System.out.printf("%d=%d%n", x, y);
    if (x != y)
      System.out.printf("%d not equal %d%n", x, y);
    if (x <= y)
      System.out.printf("%d x<=y %d%n", x, y);
  }
}

This is console below

 Value of x
 77
 value of y
 77

 ??=??
 ?? x<=y ??

Have you checked if -Dfile.encoding=UTF-8 is set in your JVM property? — lopoto, Sep 28 '18 at 11:48

Your code works fine in Intellij.

So code is correct.

Try to update your IDE.

Your code is work good in Eclipse Release 4.7.0 (Oxygen) Last revised June 28, 2017.

So you can view your properties for IDE like -Dfile.encoding=UTF-8
