如何修复我的if语句/程序

Question

我的问题是，在我的代码中，if语句应该从某个底池获取然后返回值，而是从两个底池而不是一个中获取值，无法弄清楚如何修复它。另外我的另一个问题是，每次从一个罐中取出糖果，它应该切换到另一个锅，我该怎么办呢？我正在谈论的if语句是在PassOutCandy类中。

import java.util.Random;

public class TreatHouse {
    int candyPot1; // amount of candy in pot 1
    int candyPot2; // amount of candy in pot 2
    int currentPot; // 1 or 2
    int totalCandy;
    int currentTreaters;  // variables
    int treatsPerTreater;

    public TreatHouse(int candyPot, int totalCandy) {
        // Add code here, be sure to split the candy between the pots.
      currentPot = candyPot;
      this.totalCandy = totalCandy;
      if (totalCandy <=0) {
          System.out.println("We can't give out candy if we don't have amy. I think we have some from last year. " +
                             "Yep, we have 100 pieces of candy to give out.");
          totalCandy = 100;
          candyPot1 = totalCandy/2; // splits candy between both pots and sets totalCandy to 100 if user puts in false input
          candyPot2 = totalCandy/2;
      }

      if (totalCandy > 0) {
          this.totalCandy = totalCandy;
          candyPot1 = totalCandy/2; // with correct user input splits the candy properly between both pots
          candyPot2 = totalCandy - candyPot1;
      }                            
    }

    public int getCandyCount() {
        return candyPot1 + candyPot2; // total candy left
    }

    public void passOutCandy() {
        //If there are enough treats per treater for the given amount per treater, pass out candy
        //from the current pot and switch to the other one.
        //Else display a message that the treaters have been tricked... (no candy for them.)
        // but do not change the current pot
        if ((totalCandy > 0) && (treatsPerTreater < totalCandy)) {
          if (currentPot == 1 || currentPot == 2) {
             if (currentPot == 1) {
                 candyPot1 = candyPot1 - (this.currentTreaters*this.treatsPerTreater);

             }

             if (currentPot == 2) {
                 candyPot2 = candyPot2 - (this.currentTreaters*this.treatsPerTreater);

             }
          }

          else 
              System.out.println("Pot " + currentPot + " doesn't exist. Try again next time");    
      }
      else
          System.out.println("You have been tricked! No candy for you >:D!!!!");             
    }


    //Sets the number of trick or treaters.
    public void knockKnock() {
        Random gen = new Random(System.currentTimeMillis());
        this.currentTreaters = gen.nextInt(13) + 1; //1 to 13 treaters.
    }

    //Displays how much candy in each pot, total candy left

    public void getCandyStatus() {
        //add in code here
      System.out.println("Candy in Pot1: " + candyPot1 + "  Candy in Pot2: " + candyPot2); // will display candy in pot 1 / pot 2
      System.out.println("Total candy left: " + (candyPot1 + candyPot2)); // total candy left

    }

    //returns the pot number for which candy was last given.
    public int getLastPot() {
      if (currentPot == 1 || currentPot == 2) { 
          if (currentPot == 2) { // returns the last pot that candy was taken from
              currentPot = 1;
              return currentPot;
          }
          if (currentPot == 1) {
              currentPot = 2;
              return currentPot;
          }
      }
      else 
          return currentPot;
    }

    public void setTreatsPerTreater(int treatsPerTreater) {
        //add code here
     this.treatsPerTreater = treatsPerTreater; // sets the proper amount of treats per treater from user input
    }
