people.java

软通公司培训的课件和习题里面有答案。。。

package com.iss.base;

public class People {

	
	private double height ;   // 身高
	private double weight ;   // 体重
	private double salery ;   // 工资
	
	// 默认的构造函数
	public People(){
		
	}
	
	// 带有升高和体重的构造函数
	public People(double height,double weight,double salery){
		this.height = height ;
		this.weight = weight ;
		this.salery = salery ;
	}
	
	// 方法  增加工资
	public void addSalery(){
		this.salery = salery+100 ;
		System.out.println("Salery is : " + salery);
	}
	
	
	// main函数
	public static void main(String[] args) {
		// 创建一个People的实例化对象p1
		People p1 = new People();
		// 初始化这个对象的属性:height,weight,salery
		p1.height = 1.80 ;
		p1.weight = 80;
		p1.salery = 3000 ;
		
		//	创建一个 初始化了 weight,height和saley 的 People的实例化对象p2
		People p2 = new People(1.78,71.5,2000);
		
		System.out.println("p1’s height is: " + p1.height + "m");
		System.out.println("p1’s weight is: " + p1.weight + "kg");
		
		System.out.println("p2’s height is: " + p2.height + "m");
		System.out.println("p2’s weight is: " + p2.weight + "kg");	
		
		// 每个对象都有自身的属性，对一个对象属性的更不会影响到另外一个对象
		p1.addSalery();
		p2.addSalery();
		

	}
