按字符串首位字母排序

[itzgs]

String 是=“ qod hitk 123abc bcd cde”中间用空格隔开，对其进行排序，组成新的字符串s="123abc bcd cde hitk qod"求代码！谢谢了

public static void main (String[] args) { String str="qod hitk 123abc bcd cde"; String[] strs=str.split (" "); String newStr = ""; for (int i=0;i<strs.length;i++) { for (int j = 0; j < (strs.length-i-1); j++) { if(strs[j].charAt (0)>strs[j+1].charAt (0)) { String tmp=strs[j]; strs[j]=strs[j+1]; strs[j+1]=tmp; } } } for (int i = 0; i < strs.length; i++) { newStr+=strs[i]+" "; } System.out.println (newStr); }

public static void main (String[] args)
  {
    String str="qod hitk 123abc bcd cde";
    String[] strs=str.split (" ");
    Array.sort(strs);
    //现在strs里就是排序后的
    for (int i = 0; i < strs.length; i++)
    {
      newStr+=strs[i]+" ";
    }
    System.out.println (newStr);
  }

//排序的方法
