Java频率分类器

Question

我目前在java编码频率分类器，但是无法实现正确的输出。输出应该在其频率旁边具有正确的字符，而不是字符不按频率排序。频率的输出是正确的，但字符不是。我不确定如何更改或优化我的代码。我无法使用任何java分拣机进行此分配。使用的示例输入是AAAAbbbbccdd 42424242 &&%%$#@，它应该输出

    2 freq: 4
    4 freq: 4
    A freq: 4
    b freq: 4
      freq: 2
    % freq: 2
    & freq: 2 
    c freq: 2
    d freq: 2
    # freq: 1
    $ freq: 1
    @ freq: 1 

public class Main {

public static void frequencySort(char[] beta) {
    int size = beta.length;
    int cnt;
    int l = 0;
    int cnttwo = 0;
    int temp = 0;
    int hold = 0;
    char tempChar;
    char holdChar;
    char charlie[] = new char[256];
    int countArray[] = new int[256];
    int sortedArray[] = new int[256];
    char charSorted[] = new char[256];
    char delta[] = new char[256];

    //assign beta array to charlie.
    for (int i = 0; i < size; i++) {
        charlie[i] = beta[i];
    }

    // this loop will count frequencies and store them in countArray and it
    //will store the characters in charlie.
    for (int i = 0; i < size; i++) {
        cnt = 0;
        for (int j = 0; j < size; j++) {
            if (j < i && charlie[i] == charlie[j]) {
                break;
            }
            if (charlie[j] == charlie[i]) {
                cnt++;
            }
            if (j == size - 1) {
                countArray[i] = cnt;
                delta[i] = charlie[i];
            }
        }
    }

    for( int i=0;  i<countArray.length;  i++ )
    {
        if (countArray[i] != 0)
            countArray[l++] = countArray[i];
    }

    //Here i copied the countArray to the newArray and removed the zeros
from the
    //original countArray.
    int [] newArray = new int[256];
    System.arraycopy( countArray, 0, newArray, 0, l );

    size = newArray.length;



    for (int i = 0; i < size; i++)
    {
        sortedArray[i] = 0;
        charSorted[i] = '\0';
    }
    for (int j = 0; j<size; j++)
    {
        temp = 0;
        tempChar = '\0';
