我想动态创建对象，先在List创建空对象，然后使用createEquipment复制，返回List，但是不会写了

Question

这里我应该怎么写？

package com.mvc;

import com.mvc.bean.Equipment;

import java.util.ArrayList;
import java.util.List;


public class MingleObject {

    public static List<Equipment> createEquipment(List list, String[] names,
                                            int[] amounts){
        int j = list.size();
        for (int i = 0; i < j; i++) {
            list.get(i).setName(names[i]);
            list.get(i).setAmount(amounts[i]);
        }
        return list;
    }

    public static void main(String[] args) {

        List<Equipment> strArray = new ArrayList<Equipment> ();

        Equipment switchEqu = new Equipment();
        Equipment routerEqu = new Equipment();

        strArray.add(switchEqu);
        strArray.add(routerEqu);  //向上转型

        String[] object01={"switchEqu", "routerEqu"}; // 对象变量名称

        String[] name01={"switch", "router"};// 属性

        int[] amount01={777,123}; // 属性

        MingleObject.createEquipment(strArray, name01, amount01);

        System.out.println(strArray.get(0).getName());
    }
}

package com.mvc.bean;

public class Equipment {
    private String name; // 名称
    private int amount;// 数量

    /**
     * 默认的构造方法必须不能省，不然不能解析
     */

    public Equipment(){

    }

    public Equipment(String name, int amount) {
        this.name = name;
        this.amount = amount;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public int getAmount() {
        return amount;
    }

    public void setAmount(int amount) {
        this.amount = amount;
    }

    @Override
    public String toString() {
        return "装备 [名称=" + name +
                ", 数量=" + amount +
                "]";
    }

}

Answer 1

public static List<Equipment> createEquipment(List<Equipment> list, String[] names, 
            int[] amounts){
    int j = list.size();
    for (int i = 0; i < j; i++) {
        list.get(i).setName(names[i]);
        list.get(i).setAmount(amounts[i]);
    }
    return list;
