定义一个员工类employee

定义一个员工类employee，具有属性 id(String)，属性姓名name(String)、年龄age(int)和薪水salary(float)，函数成员包括:构造函数，设置/读取id函数setId和getId，设置/读取姓名函数setName和getName，设置/读取年龄函数setAge和getAge，设置/读取薪水函数setSalary和 getSalary，输出员工基本信息的函数print。在主函数中首先创建任一员工对象emp1最后输出 emp1 的基本信息。

代码如下：

public class Employee {
    // 属性
    private int id;
    private String name;
    private int age;
    private float salary;

    // 构造函数
    public Employee() {
    }

    public Employee(int id, String name, int age, float salary) {
        this.id = id;
        this.name = name;
        this.age = age;
        this.salary = salary;
    }

    // getter and setter
    public int getId() {
        return id;
    }

    public void setId(int id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public int getAge() {
        return age;
    }

    public void setAge(int age) {
        this.age = age;
    }

    public float getSalary() {
        return salary;
    }

    public void setSalary(float salary) {
        this.salary = salary;
    }

    // 输出
    public void print() {
        System.out.println("id = " + id + ", name = " + name + ", age = " + age + ", salary = " + salary);
    }

    // main
    public static void main(String[] args) {
        Employee emp1 = new Employee(1, "zhangsan", 18, 2000);
        emp1.print();
    }
}

下面是我的思路：
1、定义四个属性：id, name，age，salary
2、定义两个构造器，一个无参，一个有四个用于参数初始化类四个属性的参数
3、分别定义四个属性的get和set方法
4、定义employee类的print方法，打印四个属性的值
6、在main方法，调用带四个参数的构造器创建对象emp1, 然后调用他的print方法打印对象emp1的基本信息。
代码如下:


public class employee {

    private String id; 
    private String name;
    private int age;
    private float salary;
    
    public employee() {
        
    }
    
    
    public employee(String id, String name, int age, float salary) {
        super();
        this.id = id;
        this.name = name;
        this.age = age;
        this.salary = salary;
    }


    
    
    public String getId() {
        return id;
    }





    public void setId(String id) {
        this.id = id;
    }





    public String getName() {
        return name;
    }





    public void setName(String name) {
        this.name = name;
    }





    public int getAge() {
        return age;
    }





    public void setAge(int age) {
        this.age = age;
    }





    public float getSalary() {
        return salary;
    }





    public void setSalary(float salary) {
        this.salary = salary;
    }




    
        

    


    
    public void print() {
        System.out.println( "id=" + id + ", name=" + name + ", age=" + age + ", salary=" + salary );
    }


    public static void main(String[] args) {
        // TODO Auto-generated method stub
        employee emp1 = new employee("20200102","张三",22,20000);
        emp1.print();
    }

}
