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 runoops"; 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 runoops ----- 通过逗号分隔 ------ This is String split by StringTokenizer created by runoops
