Limiting duplicate user input choices in consecutive If/Else

Question

How can I limit the user to spend a "Tag" on a different "Skill" on each inputFirstTag, inputSecondTag, inputThirdTag

Everything works fine until Round 2 rears its ugly head. inputSecondTag can become a duplicate of inputFirstTag, inputThirdTag can become a duplicate of inputSecondTag.

That's a lot of code. Could you be more clear on what you're trying to do? — user3340067

MaxZoom & Alp, thank you for the suggestions, I am still learning Java & have not explored/learned switch and/or reflection yet. I will research these topics more. @Amaleemur, I'm trying to make it so the user can't input the same skill for 3 rounds in a row (Example: User picks Small Guns for inputFirstTag, inputSecondTag & inputThirdTag) — JavaNewb

You could write this in a fraction of the code, by consolidating some of your very similar lines. We can give you suggestions about how to do this on codereview.stackexchange.com, although these suggestions would be out of scope for StackOverflow. Don't worry - you're doing great and we were there too. — La-comadreja

Without overwhelming you with a long block of code:

You can create a Set data structure of "taggedSkills." Initially, this Set is empty. If the user tags a skill, the skill is added to the set.

Then if the user's second tag is the same skill as the first tag, the program can check the Set and ask the user to try again with a new skill, instead of adding a duplicate tag. Same with the third skill.

This isn't perfect, and I didn't feel like typing all the choices, but this might help you.

import java.util.ArrayList;
import java.util.Scanner;

public class Meow {

public static void main(String[] args){

        ArrayList<String> choices = new ArrayList<String>();
        choices.add("Barter");
        choices.add("Repair");
        choices.add("Speech");
        choices.add("Potato");
        int[] numbers = new int[choices.size()];

    System.out.println("You have 3 Skills to Tag.");
    System.out.println("What skill would you like to Tag? (+25)");
    System.out.println("Barter, Repair, Speech, Potato?");
    Scanner scanner = new Scanner(System.in);
    String inputFirstTag = "";
    while (scanner.hasNextLine()) {
        inputFirstTag = scanner.nextLine();
        if ((choices.contains(inputFirstTag))){
            if(numbers[choices.indexOf(inputFirstTag)] == 0){
                numbers[choices.indexOf(inputFirstTag)] += 25;
                break;
            }
            else {System.out.println("Please don't choose duplicates");}
        }
        else {System.out.println("Please choose Repair, Speech, Barter.");}
    }

    System.out.println(inputFirstTag + " + 25");
    System.out.println();

    System.out.println("You have 2 Skills to Tag.");
    System.out.println("What skill would you like to Tag? (+25)");
    System.out.println("Barter, Repair, Speech, Potato?");
    String inputSecondTag = "";
    while (scanner.hasNextLine()) {
        inputSecondTag = scanner.nextLine();
        if ((choices.contains(inputSecondTag))){
            if(numbers[choices.indexOf(inputSecondTag)] == 0){
                numbers[choices.indexOf(inputSecondTag)] += 25;
                break;
            }
            else {System.out.println("Please don't choose duplicates");}
        }
        else {System.out.println("Please choose Repair, Speech, Barter.");}
    }
    System.out.println(inputSecondTag + " + 25");
    System.out.println();


    System.out.println();
    System.out.println("You have 1 Skill to Tag.");
    System.out.println("What skill would you like to Tag? (+25)");
    System.out.println("Barter, Repair, Speech, Potato?");
    String inputThirdTag = "";
    while (scanner.hasNextLine()) {
        inputThirdTag = scanner.nextLine();
        if ((choices.contains(inputThirdTag))){
            if(numbers[choices.indexOf(inputThirdTag)] == 0){
                numbers[choices.indexOf(inputThirdTag)] += 25;
                break;
            }
            else {System.out.println("Please don't choose duplicates");}
        }
        else {System.out.println("Please choose Repair, Speech, Barter.");}
    }

    System.out.println(inputThirdTag + " + 25");
    System.out.println();

    for (int i = 0; i < choices.size(); i++){
        System.out.println(choices.get(i) + " : " + numbers[i]);
    }

}

}

Amaleemur, thank you very much, I have implemented your code and it is a good learning experience. Problem is now my output looks like this: Small Guns : 0 Big Guns : 0 Energy Weapons : 0 Unarmed : 0 Melee Weapons : 0 Throwing : 0 First Aid : 25 Doctor : 25 Sneak : 0 Lockpick : 0 Steal : 0 Traps : 0 Science : 0 Repair : 25 Speech : 0 Barter : 0 Gambling : 0 Outdoors : 0

My version.
