Question

我在下面粘贴的代码是3种方法。第一种方法（maxLetterRecurrence）找到最多出现的字母，其次我想将发生次数最多的字母发送到第二个函数（printMax），这样我就可以打印出该函数中出现次数最多的字母。最后我想在我的main函数中调用print函数，也称为（secondaryMethodCalls）。出于某种原因，我无法理解它。我的计数器工作正常我的错误是在第二个方法（printMax）和第三个方法（secondaryMethodCalls）之间。请帮忙！对不起，如果缩进错误！

  import java.util.*;

 public class LetCount
{
    public static final int NUMCHARS = 27;

   // Method addr provided
   public static int addr(char ch)  
   {

   //int index[addr('ch')];
   //return (count[addr(ch)]+1);
   return (int) ch - (int) 'A' + 1; 
   }


 public static void main(String[] args)
  {
   int[] count = new int[NUMCHARS];

   secondaryMethodCalls(count);
 } // end of main
 public static void secondaryMethodCalls(int[] count)
 {
   Scanner keyboard = new Scanner(System.in);
   String sampleInput= " ";
   do{
       sampleInput = keyboard.nextLine();
       System.out.println(sampleInput);
       letterCounter(sampleInput,count);

   }while(keyboard.hasNext());   

   printMax(max);
   print(count);
  //char finalMaxLetter = maxLetterRecurrence(count);
   //char finalMinLetter = minLetterRecurrence(count);
 }
 public static void letterCounter(String sampleInput, int[]count)
 {
   int length=sampleInput.length();
   for(int i=0;i<=length-1;i++)
   {

        char ch = sampleInput.charAt(i);
        if(ch >='A' && ch <= 'Z')
       {
           count[addr(ch)]++;
       }
    }

  }//end of letter counter



   public static void print(int[]count)
  {
      for(char ch = 'A'; ch <= 'Z'; ch++)
   {
      System.out.println("letter recurrence:"+ch+"times="+count[addr(ch)]);
    }
  }

    {

    {
      min = ch;
      testVal=count[addr(ch)];
    }
  }
   return min;
  }//end of min letter counter
  public static void printMax(char max int[] count)
  {
    char finalMaxLetter = maxLetterReccurence(count);
    System.out.println("most frequent letter:"+finalMaxLetter);
  }
} // end of class

它没有用，或者你只是得到错误而无法编译？如果secon one，ofc存在问题＆＃39;最大＆＃39;未在secondaryMethodCalls中定义，并且count未在printMax中定义。只要它们不是全局变量。

方法调用和发送关闭
