本文介绍了一个简单的Java类，用于封装个人信息，如姓名、年龄、身高和体重，并提供了getter和setter方法来访问和修改这些属性。

使用快捷键ALT+insert可以快捷的调出所有的get，set方法

package com.gml;
public class Demo {
    private String name = "牛马顺";
    private int age = 18;
    private int height = 175;
    private double weight = 130.5;

    public Demo() {

    }

    public Demo(String name, int age, int height, double weight) {
        this.name = name;
        this.age = age;
        this.height = height;
        this.weight = weight;
    }

    public void setAge(int age) {
        if (age > 0) {
            this.age = age;
        } else {
            System.out.println("您输入的年龄不符合实际，请重新输入!");
        }
    }

    public int getAge() {
        return this.age;
    }

    public String getName() {
        return this.name;
    }

    public int getHeight() {
        return this.height;
    }

    public double getWeight() {
        return this.weight;
    }

    public static void main(String[] args) {
        Person p = new Person();
        p.name = "牛马顺";
        p.age = 18;
        p.height = 175;
        p.weight = 130.5;
        
        System.out.println("姓名: " + p.name);
        System.out.println("年龄: " + p.age);
        System.out.println("身高: " + p.height);
        System.out.println("体重: " + p.weight);

    }
}
