用Java定义一个person

定义一个 person 类，包括属性：姓名、性别、年
龄；定义带参数的构造方法为成员变量初始化，包括方法：吃饭（ eating )、工作（ working )、输出信息（ printInfo ）的方法。编写主类，定义主函数实例化 person 对象，测试其方法。

package com.yelang.case4;
public class Person {
    private String name;
    private String sex;
    private Integer age;

    public String getName() {
        return name;
    }

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

    public String getSex() {
        return sex;
    }

    public void setSex(String sex) {
        this.sex = sex;
    }

    public Integer getAge() {
        return age;
    }

    public void setAge(Integer age) {
        this.age = age;
    }

    public Person() {
        super();
    }

    public Person(String name, String sex, Integer age) {
        super();
        this.name = name;
        this.sex = sex;
        this.age = age;
    }

    public void eating() {
        System.out.println("eating");
    }

    public void working() {
        System.out.println("working");
    }

    public void printInfo() {
        System.out.println("name is " + this.name + " sex is " + this.sex + " age is " + this.age);
    }

    public static void main(String[] args) {
        Person person = new Person("张三", "男", 30);
        person.eating();
        person.working();
        person.printInfo();
    }
}
