定义一个Java类，用来描述订单，属性自定义

示例代码

package com.powernode.oo;

public class Order {
    /**
     * 名称
     */
    private String name;
    /**
     * 订单标识
     */
    private String productId;
    /**
     * 下单时间
     */
    private String orderTime;
    /**
     * 付款时间
     */
    private String paymentTime;
    /**
     * 支付状态
     */
    private Boolean paymentStatus;
    /**
     * 用户ID
     */
    private String userId;
    /**
     * 数量
     */
    private int number;
    /**
     * 单价
     */
    private int unitPrice;

    public Order() {
    }

    public Order(String name, String productId, String orderTime, String paymentTime, Boolean paymentStatus, String userId, int number, int unitPrice) {
        this.name = name;
        this.productId = productId;
        this.orderTime = orderTime;
        this.paymentTime = paymentTime;
        this.paymentStatus = paymentStatus;
        this.userId = userId;
        this.number = number;
        this.unitPrice = unitPrice;
    }

    public String getName() {
        return name;
    }

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

    public String getProductId() {
        return productId;
    }

    public void setProductId(String productId) {
        this.productId = productId;
    }

    public String getOrderTime() {
        return orderTime;
    }

    public void setOrderTime(String orderTime) {
        this.orderTime = orderTime;
    }

    public String getPaymentTime() {
        return paymentTime;
    }

    public void setPaymentTime(String paymentTime) {
        this.paymentTime = paymentTime;
    }

    public Boolean getPaymentStatus() {
        return paymentStatus;
    }

    public void setPaymentStatus(Boolean paymentStatus) {
        this.paymentStatus = paymentStatus;
    }

    public String getUserId() {
        return userId;
    }

    public void setUserId(String userId) {
        this.userId = userId;
    }

    public int getNumber() {
        return number;
    }

    public void setNumber(int number) {
        this.number = number;
    }

    public int getUnitPrice() {
        return unitPrice;
    }

    public void setUnitPrice(int unitPrice) {
        this.unitPrice = unitPrice;
    }
}

测试代码

package com.powernode.oo;

public class OrderTest {
    public static void main(String[] args) {
        /*
         * 创建一个订单对象，并初始化订单实例变量 
         */
        Order order = new Order("娃哈哈", "001", "2021年9月22日15点55分32秒", "2021年9月22日15点55分32秒", true, "001", 555, 50);
        System.out.println(order.getName());
        System.out.println(order.getProductId());
        System.out.println(order.getOrderTime());
        System.out.println(order.getPaymentTime());
        System.out.println(order.getPaymentStatus());
        System.out.println(order.getUserId());
        System.out.println(order.getNumber());
        System.out.println(order.getUnitPrice());

        order.setName("康师傅");
        order.setProductId("002");
        order.setOrderTime("2021年9月23日16点15分12秒");
        order.setPaymentTime("2021年9月23日16点25分12秒");
        order.setPaymentStatus(true);
        order.setUserId("002");
        order.setNumber(666);
        order.setUnitPrice(20);

        System.out.println("=========================================================");

        System.out.println(order.getName());
        System.out.println(order.getProductId());
        System.out.println(order.getOrderTime());
        System.out.println(order.getPaymentTime());
        System.out.println(order.getPaymentStatus());
        System.out.println(order.getUserId());
        System.out.println(order.getNumber());
        System.out.println(order.getUnitPrice());
    }
}
