字符串分隔(StringTokenizer)

使用 StringTokennizer 设置不同分隔符来分隔字符串，默认的分隔符是：空格、制表符（\t）、换行符(\n）、回车符（\r）。

import java.util.StringTokenizer;
 
public class Main {
    public static void main(String[] args) {
 
        String str = "This is String , split by StringTokenizer, created by runoob";
        StringTokenizer st = new StringTokenizer(str);
 
        System.out.println("----- 通过空格分隔 ------");
        while (st.hasMoreElements()) {
            System.out.println(st.nextElement());
        }
 
        System.out.println("----- 通过逗号分隔 ------");
        StringTokenizer st2 = new StringTokenizer(str, ",");
 
        while (st2.hasMoreElements()) {
            System.out.println(st2.nextElement());
        }
    }
}

输出结果：

----- 通过空格分隔 ------
This
is
String
,
split
by
StringTokenizer,
created
by
runoob
----- 通过逗号分隔 ------
This is String 
 split by StringTokenizer
 created by runoob
