Java 实例 - 字符串分隔(StringTokenizer)

Java 中我们可以使用 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)

以下实例演示了 StringTokennizer 使用空格和等号来分隔字符串:

import java.util.StringTokenizer;

public class Main {
    public static void main(String[] args) {

        String str = "This is String , split by StringTokenizer, created by nowcoder";
        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
nowcoder
----- 通过逗号分隔 ------
This is String 
 split by StringTokenizer
 created by nowcoder
