I have tried various combinations of things, and I still cannot find out why the following If statement is not executing.
| code: | if(personPlayUpper == "R" && computerPlay == "P")
{
System.out.println("Computer WINS! Paper covers Rock.");
}
else if(personPlayUpper == "P" && computerPlay == "S")
{
System.out.println("Computer WINS! Scissors cuts Paper.");
}
else if(personPlayUpper == "S" && computerPlay == "R")
{
System.out.println("Computer WINS! Rock breaks Scissors.");
}
else if(personPlayUpper == "R" && computerPlay == "S")
{
System.out.println("You WIN! Rock breaks Scissors.");
}
else if(personPlayUpper == "P" && computerPlay == "R")
{
System.out.println("You WIN! Paper covers Rock.");
}
else if(personPlayUpper == "S" && computerPlay == "P")
{
System.out.println("You WIN! Scissors cuts Paper.");
}
else if(personPlayUpper == computerPlay)
{
System.out.println("Tie game.");
} |
The entire code is below:
| code: | void q5()
{
System.out.println("Please enter R(ock), S(cissor) or P(aper)");
Scanner scan = new Scanner(System.in);
Random generator = new Random();
String personPlay;
String personPlayUpper;
String computerPlay = "N";
int computerInt = generator.nextInt(3); //Randomly generate number used to determine computer's play
personPlay = scan.nextLine(); //Get player's play -- note that this is stored as a string
personPlayUpper = personPlay.toUpperCase(); //Make player's play uppercase for ease of comparison
if(computerInt == 0) //Translate computer's randomly generated play to string
{
computerPlay = "R";
System.out.println("Computer played: Rock");
}
else if(computerInt == 1)
{
computerPlay = "P";
System.out.println("Computer played: Paper");
}
else if(computerInt == 2)
{
computerPlay = "S";
System.out.println("Computer played: Scissors");
}
System.out.println(personPlayUpper);
System.out.println(computerPlay);
if(personPlayUpper == "R" && computerPlay == "P")
{
System.out.println("Computer WINS! Paper covers Rock.");
}
else if(personPlayUpper == "P" && computerPlay == "S")
{
System.out.println("Computer WINS! Scissors cuts Paper.");
}
else if(personPlayUpper == "S" && computerPlay == "R")
{
System.out.println("Computer WINS! Rock breaks Scissors.");
}
else if(personPlayUpper == "R" && computerPlay == "S")
{
System.out.println("You WIN! Rock breaks Scissors.");
}
else if(personPlayUpper == "P" && computerPlay == "R")
{
System.out.println("You WIN! Paper covers Rock.");
}
else if(personPlayUpper == "S" && computerPlay == "P")
{
System.out.println("You WIN! Scissors cuts Paper.");
}
else if(personPlayUpper == computerPlay)
{
System.out.println("Tie game.");
}
} |
The two System.out.println commands just above the If statement execute properly, but for some reason, the If statements themselves will not.
Any help is greatly appreciated! Thanks![/code] |
