/*api解释
public StringTokenizer(String str, String delim, boolean returnDelims)
str是要处理的字符串；
delim是分隔符；
returnDelims 是否把分隔符也作为结果返回
(public StringTokenizer(String str, String delim) returnDelims默认false；
StringTokenizer(String str)默认分隔符delim是 " \t\n\r\f"，returnDelims是false)
遍历的api中注意，hasMoreElements()等于hasMoreTokens()；
nextElement()等于nextToken()。可以 看源码验证。
打印：
