@Deque
what should i do about the enum choice all i need i n my code is to print it !
what do you mean by this : "My suggestion was more for the situation where you pass it around as value."
i'll rename choice1 and choice2 to playerChoice nd pc Choice . i agree it's better!!
as for my choose winner method i prefer it as it is !!

I mean you don't need an enum for the game result if don't do anything with it.

ok so this is the final code for this game

Code:
package rockpaperscissors;

import java.util.Random;
import java.util.Scanner;

public enum Choice {

        ROCK,
        PAPER,
        SCISSORS;
    }
public class RockPaperScissors {

    public static Choice playerChoice() {
        System.out.println("choose 0 for rock");
        System.out.println("choose 1 for paper");
        System.out.println("choose 2 for scissors");
        Scanner in = new Scanner(System.in);
        int numberChosen;
        Choice choicePlayer[];
        numberChosen = in.nextInt();

        choicePlayer = Choice.values();

        return choicePlayer[numberChosen];

    }

    public static Choice pcChoice() {
        Choice[] choicePc = Choice.values();
        int rand = (new Random()).nextInt((choicePc.length));
        return choicePc[rand];
    }

    public static void chooseWinner(Choice playerChoice, Choice pcChoice) {
        if (playerChoice.equals(pcChoice)) {
            System.out.println("it's a tie");
        }
        //if player chose rock


        if ((playerChoice.equals(Choice.ROCK)) && (pcChoice.equals(Choice.SCISSORS))) {
            System.out.println("player win");
        }
        if ((playerChoice.equals(Choice.ROCK)) && (pcChoice.equals(Choice.PAPER))) {
            System.out.println("pc win");
        }

        //if player chose scissors
        if ((playerChoice.equals(Choice.SCISSORS)) && (pcChoice.equals(Choice.PAPER))) {
            System.out.println("player win");
        }
        if ((playerChoice.equals(Choice.SCISSORS)) && (pcChoice.equals(Choice.ROCK))) {
            System.out.println("pc win");
        }
        //if player chose paper
        if ((playerChoice.equals(Choice.PAPER)) && (pcChoice.equals(Choice.ROCK))) {
            System.out.println("player win");
        }
        if ((playerChoice.equals(Choice.PAPER)) && (pcChoice.equals(Choice.SCISSORS))) {
            System.out.println("pc win");
        }

    }

    public static boolean wantToPlayAgain(String playAgain) {
        boolean b1 = false;

        if (playAgain.equalsIgnoreCase("y")) {
            b1 = true;
        }

        return b1;

    }

    public static void main(String[] args) {
        String playAgain;
        String choose;
        Scanner in = new Scanner(System.in);
        do {
            // player choice
            Choice choice = playerChoice();
            System.out.println("you're choice is " + choice);

            //pc choice
            Choice pcChoice = pcChoice();
            System.out.println("pc choosed " + pcChoice);

            //choosing the winner
            chooseWinner(choice, pcChoice);
            do {
                System.out.println("Do you wanna play again y/n ?");
                playAgain = in.nextLine();
            } while (!playAgain.equalsIgnoreCase("y") && (!playAgain.equalsIgnoreCase("n")));
        } while (wantToPlayAgain(playAgain));
        System.out.println("thx for playing");
    }
}
