Java: Meier (MIA) Dice Game - Adding a Second Player

I working on a program to simulate (roughly) a Meier dice game (linked game information. I am struggling adding a second player to be rolled and have different numbers than my first player, I would think this would be done with a loop, but in this course, we haven't learned about loops yet. I am anxious on how this can be done then, since we were instructed to only use if-statements.

I'd appreciate any help on this,

Thank you!

My code:

public class Meier {   

    public static void main(String[] args) {   

    int die1=(int)(Math.random()*6+1);   
    int die2=(int)(Math.random()*6+1);  
    int rank1 = 0; // For player 1
    int rank2 = 0; // For player 2
    int temp = 0; // Allows for variable switching

    if (die1 > die2) {
        rank1 = Integer.valueOf(String.valueOf(die1) + String.valueOf(die2));
        System.out.println("Player one's two die values are: " + die1 + " and " + die2);
        System.out.println("Player one's rank is: " + rank1); }
    else if (die1 < die2) {
        temp = die1;
        die1 = die2;
        die2 = temp;
        rank1 = Integer.valueOf(String.valueOf(die1) + String.valueOf(die2));
        System.out.println("Player one's two die values are: " + die1 + " and " + die2);
        System.out.println("Player one's rank is: " + rank1); }
    else if (die1 == die2) {
        rank1 = Integer.valueOf(String.valueOf(die1) + String.valueOf(die2));
        System.out.println("Player one's two die values are: " + die1 + " and " + die2);
        System.out.println("Player one's rank is: " + rank1); }     

    return;

       }  
 }

My output:

Player one's two die values are: 6 and 1

Player one's rank is: 61
