Java中分隔字符串的方式

package com.wangbiao.split;

import java.util.StringTokenizer;

public class testSplit {

static String str = "diaoyu islands belong to China";

//用Stirng的split()来实现分隔；

public static void String_split(String str0) {

String[] s = new String[10];

s = str0.split(" ");

for (String string : s) {

System.out.println(string);

}

}

//用StringTokenizer的构造方法来实现分隔；

public static void StringTokenizer_constructor(String str0) {

StringTokenizer st = new StringTokenizer(str0, " ");

while (st.hasMoreElements()) {

String s = (String) st.nextElement();

System.out.println(s);

}

}

public static void String_split2(String str0) {

String[] s = new String[10];

s = str0.split("+");

for (String string : s) {

System.out.println(string);

}

}

public static void StringTokenizer_constructor2(String str0) {

StringTokenizer st = new StringTokenizer(str0, "+");

while (st.hasMoreElements()) {

String s = (String) st.nextElement();

System.out.println(s);

}

}

public static void main(String[] args) {

String_split(str);

StringTokenizer_constructor(str);

//特别说明，如果是用"."和"+"和"*"来分隔的话，要特别注意，"+"和"*"如果是String的split（）方法来分隔的话，要转义.而"."要用"[.]来标识；

//对于StirngTokenizer的话，不需要额外标识分隔符

/*String str2 = "diaoyu.islands.belong.to.China";

String str3="diao+yu+islands+belong+to+China";

String_split2(str2);

StringTokenizer_constructor2(str3);*/

}
