構(gòu)造函數(shù)--公司員工信息

寫一個公司員工類

1、數(shù)據(jù)成員：姓名、員工號、薪水、部門

2、方法：利用構(gòu)造方法完成設(shè)置信息

A，單參數(shù)：只傳遞姓名，則員工號和部門為未知，薪水為0.

B，雙參數(shù)：傳遞姓名和員工號，則部門為后勤部，薪水為1000.

C，四參數(shù)：傳遞姓名、員工號、部門、薪水.

D，無參數(shù)：則均為空.

顯示信息.

在main方法中創(chuàng)建四個對象，分別進(jìn)行驗(yàn)證

上代碼：

Employee

class Employ {
	
	private String name;
	private String num;
	private float salary;
	private String department;
	
	public String getName() {
		return name;
	}
	public void setName(String na) {
		this.name = na;
	}
	public String getNum() {
		return num;
	}
	public void setNum(String n) {
		this.num = n;
	}
	public float getSalary() {
		return salary;
	}
	public void setSalary(float s) {
		if(s>0){
			this.salary = s;
		}
	}
	public String getDepartment() {
		return department;
	}
	public void setDepartment(String department) {
		this.department = department;
	}
	
	public static void Emp(){
		
	}
	
	public void pmsg(){
		System.out.println("\n"+"員工信息：");
		System.out.println("姓  名："+name);
		System.out.println("員工號："+num);
		System.out.println("薪  水："+salary);
		System.out.println("部  門："+department);
	}
	
	public  Employ(String n){
		this.name=n;
		this.num="未知";
		this.salary=0.0f;
		this.department="未知";
	}
	public Employ(String n,String nu){
		this.name=n;
		this.num=nu;
		this.salary=1000.0f;
		this.department="開發(fā)部";
	}
	public Employ(String n, String nu, float s, String d){
		this.name=n;
		this.num=nu;
		this.salary=s;
		this.department=d;
	}
	public Employ(){
		this.name="";
		this.num="";
		this.salary=0.0f;
		this.department="";
	}

}


public class Employee{
	public static void main(String[] args){
		Employ e1=new Employ("張三","E001",888,"后勤部");
		Employ e2=new Employ("李四","E002");
		Employ e3=new Employ();
		Employ e4=new Employ("王五");
		
		e1.pmsg();
		e2.pmsg();
		e3.pmsg();
		e4.pmsg();
	}
}
