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]);

		}

	}

}
