StringTokenizer

public StringTokenizer(String str, String delim, boolean returnDelims)

 1 int countTokens()//返回nextToken方法被调用的次数。如果采用构造函数1和2，返回的就是分隔符数量。
 2 
 3 boolean hasMoreTokens() //返回是否还有分隔符。
 4 
 5 boolean hasMoreElements()//返回是否还有分隔符。
 6 
 7 String nextToken()//返回从当前位置到下一个分隔符的字符串。
 8 
 9 Object nextElement() //返回从当前位置到下一个分隔符的字符串。
10 
11 String nextToken(String delim)//与上面类似，以指定的分隔符返回结果。
