字符排序程序

public class rrrr { public static void main(String args[]) { String str = "p9z1gxy32jm0wq4uf6mbrva5ie8sd7clkto"; String str2 = ""; char tempstr = 0; char[] arrstr = str.toCharArray();//把字符串转换为字符数组 for(int i = 0;i < arrstr.length;i++)//冒泡程序，由小到大排序 { for(int j = 0;j < arrstr.length - 1;j++) { //System.out.print(arrstr[j]); if(arrstr[j] > arrstr[j+1]) { tempstr = arrstr[j]; arrstr[j] = arrstr[j+1]; arrstr[j+1] = tempstr; } } } for (int k = 0;k < str.length();k++)//循环数组返回结果到字符串 { if(str2 != "") str2 += arrstr[k]; else str2 = arrstr[k]+""; } System.out.println(str2);//显示 } }
