字符串中还有空格去掉空格转化成字符串数组然后在转化成数字数组排序

 package com.accp.util;
import java.util.Arrays;
public class Test {

 public Test() {
  // TODO Auto-generated constructor stub
 }

 /**
  * @param args
  */
 

 public static void main(String[] args) {
  // TODO Auto-generated method stub
  String dd="21 1 8 50 98 100 50";
   String[] sum =dd.split(" ");  //去除空格转化成字符串数组
   //  String[] sum ={"ac","ca","bk","w","d1"};
      //
      double []a=new double[7];
      try{
         for(int i=0;i<sum.length;i++){
        
         a[i] = Double.parseDouble(sum[i]);
         }
      }catch(Exception ex){
       
      }
      Arrays.sort(a);
        for(int i = 0;i<a.length;i++){
             System.out.println(a[i]);
        }  

 }
