java中StringTokenizer用法举例

package test;

import java.util.StringTokenizer;

public class StringTokenizerTest {

	/**
	 * @param args
	 */
	public static void main(String[] args) {
		String s = "I am zhangwuji , she is my friends";
		StringTokenizer fx = new StringTokenizer(s," ,");//分别使用空格 逗号作为分隔符
		int number = fx.countTokens();
		while(fx.hasMoreTokens()){
			String str = fx.nextToken();
			System.out.println("当前单词："+str);
			System.out.println("还剩"+fx.countTokens()+"个单词");
		}
		System.out.println("共有单词"+number+"个");
		
	}

	private static void defaultTokenizer() {
		//java中如果没有指定分隔符，默认是空格
		String str = "this is a java program";
		StringTokenizer st = new StringTokenizer(str);
		while(st.hasMoreTokens()){
			System.out.println(st.nextToken());
		}
		System.out.println("**************************");
		//st.hasMoreElements 用法 作用同上,只能写一个，st被调用后就到达分割末尾了
//		while(st.hasMoreElements()){
//			System.out.println(st.nextElement());
//		}
	}
