java ObjectOutputStream 对象的序列化 Serializable

第一步 新建一个类继承Serializable接口

public class Goods implements Serializable{

private String goodsId;

private String goodsName;

private double price;

public String getGoodsId() {

return goodsId;

}

public void setGoodsId(String goodsId) {

this.goodsId = goodsId;

}

public String getGoodsName() {

return goodsName;

}

public void setGoodsName(String goodsName) {

this.goodsName = goodsName;

}

public double getPrice() {

return price;

}

public void setPrice(double price) {

this.price = price;

}

public Goods(String goodsId, String goodsName, double price) {

super();

this.goodsId = goodsId;

this.goodsName = goodsName;

this.price = price;

}

@Override

public String toString() {

return " [商品编号=" + goodsId + ", 商品名称=" + goodsName + ", 商品价格=" + price + "]";

}

}

第二步:新建测试类 对上一个类进行读写操作
