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());
//}
}

}
