PigDice java错误

Question

好吧，所以我必须编写一个程序猪骰子，我大部分都完成并运行，但最大的问题是，分数不添加，我真的需要帮助，它使用面值从一个独立程序Die是随机生成的。

import java.util.Scanner; 

public class pigDiceGame 
{ 
public static void main(String[]args) 
{ 
    // This section will ask the user is they know how to play the game of      Pig Dice 

    System.out.println("You are Going to Play the Pig Dice Game!"); 
    System.out.println(""); 
    System.out.println(""); 
    System.out.println("Do You Know the rules?...if not press 1...otherwise press any key to continue."); 

    // This sectionwill allow the user to input whether they want to read the rules or not 
    Scanner scanner = new Scanner (System.in); 
    int rules = scanner.nextInt(); 

    // This sectionwill actually explain the rules of the game 
    if (rules == 1) 
    { 
    System.out.println(""); 
    System.out.println(""); 
    System.out.println("Rules..."); 
    System.out.println(""); 
    System.out.println(""); 
    System.out.println("1. In one turn the player rolls the dice until either"); 
    System.out.println(" -They roll a one"); 
    System.out.println(" -Or they choose to stop"); 
    System.out.println("2. You add up the numbers on the dice and are trying             to reach 100."); 
    System.out.println("3. Rolling a 1 will clear your points for that turn."); 
    System.out.println("4. If you choose to stop you can keep the points you have earned."); 
    System.out.println("5. Rolling a pair counts double points"); 
    System.out.println(""); 
    System.out.println(""); 
    } 
    System.out.println("Lets begin..."); 
    System.out.println(""); 
    System.out.println(""); 



    // all the variables I am using in the game are here

您稍后重新声明你的变量。你只需要实例化一次，每个变量，否则它被设置为0

int score=faceValue1+faceValue2; // (line 71) 
int score=0; // (line 132) 

它可能会更容易为你管理，看看发生了什么事情，如果你声明所有的变量在最顶部你的功能和方法。
