Making my first project in java

Question

So after like 2 hours of Java guides I started making my first project, a simple rock paper scissors game, but then I found a problem. I want to add 1 point to the winner of the game each time you pick rock paper or scissors and you win and its the only thing I need to do before its completed (I am new to Java).

You have an error in

public static void setUserCounter(int userCounter) {
    Main.userCounter = userCounter + userCounter;
}

Should be

Main.userCounter += userCounter;

or

Main.userCounter = Main.userCounter + userCounter;

Same thing for:

public static void setPcCounter(int pcCounter) {
    Main.pcCounter = pcCounter + pcCounter;
}

Also in some places at the bottom, you use directly the userCounter variable without using setUserCounter();

} else if (user == SCISSORS && pc == PAPER) {
update.setText(user + " vs " + pc + " You Win!!");
userCounter += 1;

Keep your style consistent and use setUserCounter();

Note that in objects, when there is myVar Object field and myVar argument, the Object field can be accessed by typing "this.myVar" to differentiate it from the argument which is "myVar"
