勤奋学习java，有个关于StringTokenizer的问题import java.util.*;
class MyTest
{
public static void main(String[] args)
{
String MyString="I love you. a b c s e f g ";
System.out.println(my1(MyString,7));
System.out.println(my1(MyString,2));
}
public static String my1(String s, int k)
{
StringTokenizer st=new StringTokenizer(s," \t\n\r,.;:");
String f=null;
for(int i=0;i.<
哪个学长教教我
谢谢了先

Come in-->>
//for(int i=0;i<=st.countTokens();i++)
here you can't use countTokens as loop condition, because it varies during execution. Once nextToken() executes once, the value of countTokens() decrements by one
