Stumped on program project

[Mr Q]

I am trying to writing a program that does the Rock Paper Scissor game, against the computer
using keyboard input, and the buffered reader. also keeping track of wins, loses, ties

I managed to get the input through the buffered reader, the problem is I am stumped on what the next step is. any help would be appreciated.


also when compiling I get these two errors:
rps2.java: 44: illegal start of expression else if(player === PAPER)
^
rps2.java:59: ')' expected }

import java.io.*;
import java.util.*;

public class rps2
{		
		final int ROCK = 0, PAPER = 1, SCISSORS = 2;
		int computer, player;
		int COMP = 0, PLAYER = 0;
		int Cwins, Closses, Pwins, Plosses,ties, winner = 0;
		
	public static void main (String [] args)throws IOException
	{
		String string_1;
		
		System.out.println("Enter *0*-Rock | *1* Paper | *2*Scissors : ");
		BufferedReader stdin =
			new BufferedReader( new InputStreamReader(System.in));		
		
		string_1 = stdin.readLine();
        int player =  Integer.parseInt(string_1);     
		getUserInput();
	}	
	public void getUserInput()
	{	
		computer = getRandom();
	
		switch(computer)
		{
		case ROCK:
			if (player === SCISSORS )
			{
				System.out.println("Computer Wins");
				break;
			}
			else if (player == PAPER)
			{
				System.out.println("Player WINS");
				break;
			}
			else
			{
				System.out.println("Tie");
				break;		
			}
		}		
	}
	
	public int getRandom()
	{
		return  (int)(Math.random()*3)+1;
	}	
}

When checking equality, you're using 3 '=' rather than 2 i.e. '===' rather than '=='.

The methods getUserInput() and getRandom() should be declared static as a static method (such as main) cannot directly call a non-static one.

All of your instance variables must be declared static because once you've made getUserInput() static, they cannot be referenced from a static method.

Also it's a convention in Java to declare classes with a capital letter i.e. 'RockPaperScissor' rather than 'rockpaperscissor' or 'rps'.

It's also not a good idea to name variables such as 'string_1' - the name isn't very helpful.

Unless variables are to be used outside a class (such as 'ROCK') they should be declared private.

thanks for advice and tips ArchAngel much appreciated

i am still learning the conventions of java,
the static is what i am having a problem with though.

so the variables should be
int static computer

correct?
Peace

No, you have the wrong syntax:

  private static int computer;

'static' BEFORe 'int'.
