用java编程：设计一个Worker类和Address类，类的要求如下： （1）定义一个Worker类，类中定义三个属性：姓名、年龄、工资（salary），要求如下： ①提供公开无参构造方法和三个参数的构造方法 2 定义无参的work方法和带整数参数work（inthours）方法，参数代表工人工作的小时数

好的，这里是Java代码实现：

// Address类
public class Address {
    private String street;
    private String city;
    private String state;
    private int zipCode;

    public Address(String street, String city, String state, int zipCode) {
        this.street = street;
        this.city = city;
        this.state = state;
        this.zipCode = zipCode;
    }

    // getter和setter方法
    public String getStreet() {
        return street;
    }

    public void setStreet(String street) {
        this.street = street;
    }

    public String getCity() {
        return city;
    }

    public void setCity(String city) {
        this.city = city;
    }

    public String getState() {
        return state;
    }

    public void setState(String state) {
        this.state = state;
    }

    public int getZipCode() {
        return zipCode;
    }

    public void setZipCode(int zipCode) {
        this.zipCode = zipCode;
    }
}

// Worker类
public class Worker {
    private String name;
    private int age;
    private double salary;

    public Worker() {
    }

    public Worker(String name, int age, double salary) {
        this.name = name;
        this.age = age;
        this.salary = salary;
    }

    public void work() {
        System.out.println(name + " is working.");
    }

    public void work(int hours) {
        System.out.println(name + " is working for " + hours + " hours.");
    }

    // getter和setter方法
    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 double getSalary() {
        return salary;
    }

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

以上代码中，Address类表示地址信息，Worker类表示一个工人，包含姓名、年龄、工资三个属性，还有work和work(int hours)两个方法。其中work方法表示工人工作，不带参数；work(int hours)方法表示工人工作，带一个整数参数，表示工人工作的小时数。这里我们使用了构造方法和getter、setter方法来初始化和获取属性值。
