split的另外一种用法StringTokenizer

      String softName="asa|asdasd|cddd|q|qq";      
      StringTokenizer commaToker = new StringTokenizer(softName, "|");
      String[] arr = new String[commaToker.countTokens()];
       for(int   i=0;commaToker.hasMoreTokens();i++)  
                  {
                   arr[i]=commaToker.nextToken();  
                  }
      String version=arr.length==0?arr[0]:arr[1];
