定义一个职工类Employee在main方法调用构造方法
1、创建工程,包,类。。。
2、首先创建一个职工类Employee(public class Employee{)
定义初始化变量
(String name,sex,department;
int age,no;)

3、构造方法:无参(public Employee(){};)
三参(
public Employee(String name, int no, String department){
this.name=name;
this.no=no;
this.department=department;
}
)
五参(
public Employee(String name, String sex, int age, int no, String department){
this.name=name;
this.sex=sex;
this.age=age;
this.no=no;
this.department=department;
}
)

4、创建一个work方法用于格式输出(
public void work(){
System.out.println("该职工姓名为:"+name+"\t"+"性别:"+sex+"\t"+"年龄:"+age+"\t"
+"工号:"+no+"\t"+"所属部门:"+department);
}
)

5、输入对象数据并输出(
public static void main(String[] args){
Employee E1=new Employee();
E1.work();
Employee E2=new Employee("小明",20171102,"信息系");
E2.work();
Employee E3=new Employee("小红","女",20171103,18,"信息系");
E3.work();
}
}
)
