JAVA * 定义私有属性： * 字符串名称;* 整数年龄;* 字符串性别;* 国际工资;* Date hiredate;//入职时间 * * 定义构造方法，以及属性get，set方法.* 定义toString方法，格式如： * 姓名：张三，年龄：25，性别：男，薪资：5000，入职时间：2006-02-15 * * 定义等于方法，要求只要相同，则认为名字内容一致。并测试

以下是JAVA代码的实现：

import java.util.Date;

public class Employee {
    private String name;
    private int age;
    private String gender;
    private int salary;
    private Date hiredate;

    public Employee(String name, int age, String gender, int salary, Date hiredate) {
        this.name = name;
        this.age = age;
        this.gender = gender;
        this.salary = salary;
        this.hiredate = hiredate;
    }

    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 String getGender() {
        return gender;
    }

    public void setGender(String gender) {
        this.gender = gender;
    }

    public int getSalary() {
        return salary;
    }

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

    public Date getHiredate() {
        return hiredate;
    }

    public void setHiredate(Date hiredate) {
        this.hiredate = hiredate;
    }

    @Override
    public String toString() {
        return "姓名:" + name + ", 年龄:" + age + ", 性别:" + gender + ", 薪资:" + salary + ", 入职时间:" + hiredate.toString();
    }

    @Override
    public boolean equals(Object obj) {
        if (this == obj) {
            return true;
        }
        if (obj == null || getClass() != obj.getClass()) {
            return false;
        }
        Employee employee = (Employee) obj;
        return name.equals(employee.name);
    }

    public static void main(String[] args) {
        // 创建两个Employee对象
        Employee employee1 = new Employee("张三", 25, "男", 5000, new Date(2006, 1, 15));
        Employee employee2 = new Employee("张三", 30, "男", 6000, new Date(2010, 5, 20));

        // 测试toString方法
        System.out.println(employee1.toString());
        System.out.println(employee2.toString());

        // 测试equals方法
        System.out.println("employee1和employee2是否内容相同：" + employee1.equals(employee2));
    }
}

上述代码中定义了`Employee`类，包含了私有属性`name`、`age`、`gender`、`salary`和`hiredate`。构造方法用于初始化对象，属性的get和set方法用于获取和设置属性的值。`toString`方法用于返回对象的字符串表示，格式为所需的输出格式。`equals`方法用于判断两个对象是否内容相同，只要名字相同即认为内容一致。在`main`方法中，我们创建了两个Employee对象，并测试了`toString`方法和`equals`方法。
