计算方法中的出现次数 [英] counting occurances in a method

问题描述

im创建了一种方法来计算另一种方法中随机字符的出现，但是我似乎无法弄清楚如何从另一种方法中引入随机字符，代码应该创建一个由26个整数组成的数组，然后进行计数和存储随机字符的出现，这是我到目前为止的代码:

im creating a method that counts the occurances of random characters in another method but i cant seem to figure out how to bring in the random characters in from the other method the code is supposed to create an array of 26 integers then count and store the occurances of the random characters this is my code up until now:

      // generates random characters
public void add (char fromChar, char toChar){      
int range = toChar - fromChar;
int seed = fromChar * toChar;
Random rr = new Random(seed);
for (int i = 0; i < charArray; ++i) {
    char randomChar = (char)(fromChar + rr.nextInt(range));
    System.out.println("Next character: " + randomChar);
}   
 
public int[] countLetters(){ //method im working on
        int [] countLetters =new int[26];
       char current;
       
for(int i=0; i<countletters.length;>   current=.charAt(i);
    if (current >= 'a' && current <= 'z'){
       countLetters[current-'a']++;
   }
}
        return null;   
    }

推荐答案

您可以创建要搜索成员变量的数组，或者最好将其作为参数传递.

You make the array you want to search a member variable or, better yet, pass it in as a parameter.
