i had a quick question, so i finished up writing my program which is a simple Rock, Paper Scissors game but at the moment it only displays 0,1,2 which 0 is scissors, 1 is rock, and 2 is paper. The problem im having is that im not quite sure how to give the users input as well as what the computer outputs go from displaying numbers to displaying scissors, rock, paper.
import java.util.Scanner;
import java.lang.Math;
public class Lab3
{
public static void main(String[] args)
{
Scanner in = new Scanner(System.in);
System.out.print("Hello user! lets play ");
System.out.println("Rock, Paper, Scissors.");
System.out.println();
System.out.print("Type in 0 for Scissors, 1 for Rock, or 2 for Paper ");
int userInput = in.nextInt();
int opponentsHand = (int)(Math.random()*3);
if (userInput == opponentsHand)
{
System.out.print("Darth Vader has played " + opponentsHand);
System.out.println(" Despite your efforts of playing " + userInput + ", this battle has ended in a draw!");
}
if (userInput < opponentsHand && opponentsHand != 2)
{
System.out.print("Darth vader has played "+ opponentsHand);
System.out.println(", You played " + userInput + "You have Lost");
}
else if (userInput < opponentsHand && opponentsHand == 2)
{
System.out.print("Darth Vader has played " + opponentsHand);
System.out.println(" You played " + userInput + " You have won");
}
if (userInput > opponentsHand && opponentsHand != 0)
{
System.out.print("Darth Vader has played " + opponentsHand);
System.out.println(" You have played " + userInput + " You have won");
}
else if (userInput > opponentsHand && opponentsHand == 0)
{
System.out.print("Darth Vader has played " + opponentsHand);
System.out.println(" You have played " + userInput + " You have lost");
}
}
}
thank you
One way is to simply use an array to store the names of the hands:
String[] hands = {"scissors", "rock", "paper"};
When you print, you do the following:
System.out.print("Darth Vader has played " + hands[opponentsHand]);

How do I compare strings in Java?

Closed 6 years ago.
I created this program to run infinite times asking the user to enter a choice(rock or paper or scissor), which seems to work fine. The problem is no else ....if or if ....else statements are satisfied. Whatever input i give it just prints out the else statement in the else statement, (Enter a valid choice). I cant find the mistake i made so ill link my code below..... Thanks in advance.

System.out.println("Take your pick \nrock \npaper \nscissor");

System.out.println(ai);

}
}
}
}
Instead of :
if(player == "rock" && ai == "paper"){
...
}
Use
if(player.equals("rock") && ai.equals("paper")){
...
}
This will apply to all of your pieces of code which compare Strings.
In java, == tests for reference equality: if the two objects are actually the same object. Two strings holding the same characters will fail this check, which is what's happening in your logic.
See How do I compare strings in Java?
I'm trying to make a rock-paper-scissors program that is a best two out of three where the computer randomly rolls a 0-2 and each of those are assigned to rock, paper, or scissors, and then it compares the userInput and counts a win for computer or player then adds it up.
BUT, I can't figure out how to make it that if user were to enter "scissors" the program would know that it's also assigned to 2 (For comparison purposes).
public static void main(String[] args) {
Random r = new Random();
int gameCount = 0;
int computerWins = 0;
int playerWins = 0;
int rock = 0;
int paper = 1;
int scissors = 2;
int playerChoice;
int computerChoice = r.nextInt(3);
System.out.println("Welcome to Rock Paper Scissors! Best 2 out of 3!");
while (gameCount >= 0 && gameCount < 3)
{
System.out.println("Enter \"Rock\", \"Paper\", or \"Scissors\"");
break;
}
playerChoice = userInput.nextInt()
//If player enters anything besides rock, paper, or scissors
if (playerChoice < 0 || playerChoice >= 3) {
System.out.println("That wasn't an option");
computerWins++;
gameCount++;
//The game goes on, and the winners are added up!
} else if (playerChoice == 0 && computerChoice == 1) {
computerWins++;
gameCount++;
System.out.println("Rock v Paper! Computer Wins!\n" +
"Player has won " + playerWins + " times and the computer " +
"has won " + computerWins + " times");
} else if (playerChoice == 1 && computerChoice == 0) {
playerWins++;
gameCount++;
System.out.println("Paper v Rock! Player Wins!\n" +
"Player has won " + playerWins + " times and the computer " +
"has won " + computerWins + " times");
} else if (playerChoice == 1 && computerChoice == 2) {
computerWins++;
gameCount++;
System.out.println("Paper v Scissors! Computer Wins!\n" +
"Player has won " + playerWins + " times and the computer " +
"has won " + computerWins + " times");
} else if (playerChoice == 2 && computerChoice == 1) {
playerWins++;
gameCount++;
System.out.println("Scissors v Paper! Player Wins!\n" +
"Player has won " + playerWins + " times and the computer " +
"has won " + computerWins + " times");
} else if (playerChoice == 2 && computerChoice == 0) {
computerWins++;
gameCount++;
System.out.println("Scissors v Rock! Computer Wins!\n" +
"Player has won " + playerWins + " times and the computer " +
"has won " + computerWins + " times");
} else if (playerChoice == 0 && computerChoice == 2) {
playerWins++;
gameCount++;
System.out.println("Rock v Scissors! Player Wins!\n" +
"Player has won " + playerWins + " times and the computer " +
"has won " + computerWins + " times");
} else if (playerChoice == 0 && computerChoice == 0) {
gameCount++;
System.out.println("Rock v Rock! Tie!\n" +
"Player has won " + playerWins + " times and the computer " +
"has won " + computerWins + " times");
} else if (playerChoice == 1 && computerChoice == 1) {
gameCount++;
System.out.println("Paper v Paper! Tie!\n" +
"Player has won " + playerWins + " times and the computer " +
"has won " + computerWins + " times");
} else if (playerChoice == 2 && computerChoice == 2) {
gameCount++;
System.out.println("Paper v Paper! Tie!\n" +
"Player has won " + playerWins + " times and the computer " +
"has won " + computerWins + " times");
}
//Check if game count reaches max games then chooses a winner
if (gameCount == 3 && computerWins > playerWins) {
System.out.println("The Computer Wins!");
} else if (gameCount == 3 && computerWins < playerWins) {
System.out.println("The Player Wins!");
} else if (gameCount == 3 && computerWins == playerWins) {
System.out.println("The game is a tie!");
}
}
}
So instead of playerChoice = userInput.nextInt(); try this:
Scanner sc = new Scanner(System.in);
String input = sc.nextLine();
try {
playerChoice = Integer.parseInt(input);
} catch (NumberFormatException e) {
if (input.equalsIgnoreCase("rock")) {
playerChoice = rock;
} else if (input.equalsIgnoreCase("paper")) {
playerChoice = paper;
} else if (input.equalsIgnoreCase("scissors")) {
playerChoice = scissors;
} else {
// if input is invalid
playerChoice = -1;
}
}
Since you're using userInput.nextInt() and playerChoice is an int and can only hold ints, you need to parse your user's input. In this case, Integer.parseInt(input) will try to find an int in the user input. If it can't it will return an exception; that's why there's a try-catch block. If it isn't an int, it will look for each string and assign the associated int value to playerChoice or -1 if the input is invalid. Then the rest of your code should be able to appropriately handle the playerChoice after that.
The code is below. My program runs smoothly except for two issues. It does not play for just three rounds and I need it to play for just 3 rounds and determine a winner based off of whoever won at least once during the three rounds despite ties (if it comes down to that scenario randomly). It plays until there is a 2 to 1 winning ratio for either the player or the computer. I do not want it to run continuously like this. The other issue is that once a final winner is declared, the line “Enter rock, paper, or scissors” appears again, and it is not needed there. How do I go about fixing these two issues? Thank you.

The code looks like it should work the way you want it to, aside from the fact that in the case of ties, you aren't incrementing the round counter:
if(USER == PC){
if(USER == SCISSOR){
System.out.println("Scissors v Scissors! Tie!");
rnd++;
}
if(USER == ROCK){
System.out.println("Rock v Rock! Tie!");
rnd++;
}
if(USER == PAPER){
System.out.println("Paper v Paper! Tie!");
rnd++;
}
System.out.println("Player has won " + wins + " times and the computer has won " + losses + " times");
System.out.print("Enter \"Rock\", \"Paper\" or \"Scissors\" \n");
}
As a side note, you could take out the rnd++; from each individual result, and have it increase every time you get input from the user, since you want it to increase no matter what.
Your second issue stems from the fact that you're prompting for new input every time you receive input, after you tell the user the result, including the ending result. You could fix this by removing the prompt command from the individual results and placing it at the beginning of your while loop instead. Note that if you do this, you may also want to remove the prompt from your welcome message as well, or it will prompt twice at the beginning: once in the welcome message, and again when the while loop starts immediately after.

Is there a better algorithm I can implement rather than using the three separate conditions within my else-if statement? Also, instead of having the 'zero' string in my array, how could I check through my array using only numbers 1, 2, and 3?
Just use
String[] choice = { "rock" , "paper" , "scissors" };
Then instead of choice[userChoice] you can do choice[userChoice - 1].
You don't need to write
if ( ( compChoice == 1 && userChoice == 3 )
|| ( compChoice == 2 && userChoice == 1 )
|| ( compChoice == 3 && userChoice == 2) )
because it is the same as
if (compChoice == 1 + (userChoice % 3))

I you convert your if statements to combined if else if statements than what is left in your else case will be the tie.
if(winRow1('O' , ttt))
System.out.println("Your game " + gameNum + ": O won the game by row 1");
else if(winRow2('O' , ttt))
System.out.println("Your game " + gameNum + ": O won the game by row 2");
.
.
.
else
System.out.println("Your game " + gameNum + ": It is a tie");
By the way,this way you could avoid multiple messages like when there are one row and one column fulticked at the same time ;).
