split的用法回顾，快忘记了@ →@

split:用for循环时不要忘记是数组名.length

package com.aaa;

//split的用法把指定的字符串按指定的分割符进行分割，然后返回字符串 数组
public class fgsd {
	public static void main(String[] args) {
		String a = "this is my  subject";// 结果显示少了个字母。对头了
		String b[] = a.split(" m", 23);
		for (int i = 0; i < b.length; i++) {
			System.out.println(b[i]);
		}
	}

}
