java-字符串中的字符进行排序

主要用了两个排序方法，冒泡排序和选择排序。
示例代码：

package cn.lgt.sortarray;

public class ZifuSort {
    public static void main(String[] args) {
        String str1 = "gdeacbf";
        char[] chs1 = str1.toCharArray();
        // 排序方法
        //冒泡排序
        maoPaoSort(chs1);
        String result = String.valueOf(chs1);
        System.out.println("result = " + result);
        //选择排序
        String str2 = "hmgdeacbf";
        char[] chs2 = str2.toCharArray();
        xuanZeSort(chs2);
        String result2 = String.valueOf(chs2);
        System.out.println("result2 = " + result2);

    }

    // 冒泡排序方法
    public static void maoPaoSort(char[] chs) {
        for (int i = 0; i < chs.length - 1; i++) {
            for (int j = 0; j < chs.length - 1 - i; j++) {
                if (chs[j] > chs[j + 1]) {
                    char temp = chs[j];
                    chs[j] = chs[j + 1];
                    chs[j + 1] = temp;
                }
            }
            //String str1 = String.valueOf(chs);
            //System.out.println(str1);
        }
    }

    //选择排序算法
    public static void xuanZeSort(char[] chs){
        for(int i = 0; i < chs.length-1; i++){
            for(int j = i+1; jif(chs[j] < chs[i]){
                    char temp = chs[j];
                    chs[j] = chs[i];
                    chs[i] = temp;
                }
            }
        }
    }

}
