Java编译错误:找不到符号 [英] Java compile error: symbol cannot be found

问题描述

我的任务是这样的:

创建一个满足以下要求的Java程序:

Create a Java program that satisfies the following requirements:

• 创建一个名为 MaxScore.java 的 Java 源文件
• 创建一个名为 MaxScore 的类
• MaxScore 类有两种方法:
  • 主要
  • maxScore

  maxScore 方法接受七个整数参数调用时，maxScore 方法返回七个输入参数中最大的一个

  The maxScore method takes seven integer arguments When called, the maxScore method returns the largest of the seven input arguments

  main 方法执行以下步骤七次:

  The main method performs the following steps seven times:

  • 写入标准输出:输入分数:
  • 从 STDIN 读取一个整数值并将其存储在一个新变量中
  • main 方法使用从标准输入
  • main 方法写入 STDOUT 中的最高分如下格式:最高分是:

  我的主要问题是符号未定义.我已经尝试了很多次，但都没有运气.我敢肯定这是一个相当容易解决的问题，但我真的很感激一些帮助.这是我的代码:

  My main problem is that the symbol is not defined. I have tried this a bunch of times with no luck. I'm sure it's a fairly easy to fix problem but I could really appreciate some help. Here is my code:

      import java.util.Scanner;
  
      public class MaxScore1{
  public static void main(String[] args){ 
  //establishes the main method first
  int z = a,b,c,d,e,f,g; 
  
      z = maxScore(a,b,c,d,e,f,g); 
  
      Scanner foo = new Scanner( System.in ); 
      //repeating the code 7 times in order to get 7 integers that are the scores
      System.out.print("Enter a score: ");
      a = foo.nextInt();
      System.out.print("Enter a score: ");
      b = foo.nextInt();
      System.out.print("Enter a score: ");
      c = foo.nextInt();
      System.out.print("Enter a score: ");
      d = foo.nextInt();
      System.out.print("Enter a score: ");
      e = foo.nextInt();
      System.out.print("Enter a score: ");
      f = foo.nextInt();
      System.out.print("Enter a score: ");
      g = foo.nextInt();
      System.out.println("Maximum value returned by maxScore is " + z + "."); 
  
      }
  public static int maxScore(int a,int b,int c,int d,int e,int f,int g){ 
  //calling all the integers obtained earlier
      int x; 
      //establishing a base for the currentscore
      x = 0;
      //establishing the variable
      if (a > x){ 
      //a set of if statements to return the maximum value
          x = a;
          }
      if (b > x){
          x = b;
          }
      if (c > x){
          x = c;
          }
      if (d > x){
          x = d;
          }
      if (e > x){
          x = e;
          }
      if (f > x){
          x = f;
          }
      if (g > x){
          x = g;
          }
      return x; //returning the maximum value obtained.
      }
  

  }

  我的错误是:

      MaxScore1.java:6: error: cannot find symbol
      int z = a,b,c,d,e,f,g;
              ^
        symbol:   variable a
        location: class MaxScore1
       MaxScore1.java:8: error: cannot find symbol
              z = maxScore(a,b,c,d,e,f,g);
                           ^
       symbol:   variable a
       location: class MaxScore1
      MaxScore1.java:13: error: cannot find symbol
              a = foo.nextInt();
              ^
        symbol:   variable a
        location: class MaxScore1
       3 errors
  

  推荐答案

  你应该正确声明你的变量 int z,a,b,c,d,e,f,g; 并计算仅在您读入所有值后 获得最大分数.

  You should declare your variables correctly int z,a,b,c,d,e,f,g; and calculate the max score only after you read in all the values.
