扩展的数组列表工具类
构造时可用数组初始化

package com.cuihongming;

import java.util.ArrayList;

public class MyArrayList extends ArrayList {

    private static final long serialVersionUID = 125204210876761836L;

    public MyArrayList(E[] e1){
        super();
        for(E e : e1) {
            this.add(e);
        }
    }
}

自定义的错误||非法输入异常类
