一个java简单类的书写，闲时可以拿来练手（要求一次性编译通过）

class Employer{
//定义属性：姓名，性别，职位，工资，编号,要用private 封装
private String name;
private String sex;
private String job;
private double salary;
private int id;

//写构造器：注意要有无参构造器
public Employer(){}
public Employer(String name,String sex,String job,double salary,int id){
this.name = name ;
this.sex = sex;
this.job = job;
this.salary = salary;
this.id = id;
}
//写setter和getter
public void setName(String name){
this.name = name;}
public void setSex(String sex){
this.sex = sex;}
public void setJob(String job){
this.job = job;}
public void setSalay(double Salary){
this.salary = salary;}
public void setId(int id){
this.id = id;}
public String getName(){
return name;}
public String getSex(){
return sex;}
public String getJob(){
return job;}
public double getSalary(){
return salary;}
public int getId(){
return id;}
//写方法，包括getInfo()
public String act(){
return "张全蛋正在工作!";
}
public String realax(){
return"张全蛋正在休息！";
}
public String getInfo(){
return  "员工姓名："+name+"\n"+
"员工性别："+sex+"\n"+
"员工职位："+job+"\n"+
"员工薪水："+salary+"\n"+
"员工编号："+id;
}

}

public class Demo{
public static void  main(String args[]){
//声明并实例化一个对象a
Emp a = new Emp("张全蛋","女","32号充气娃娃流水线装填工人",2222.22,250);
System.out.println(a.getInfo()+"\n"+a.act());

//调用setSex方法改变性别
a.setSex("男");
System.out.println("\n"+a.getInfo()+"\n"+a.realax());
}

}
