已知有一个Worker 类如下： public class Worker { private int age; private String name; private double salary; public Worker (){} public Worker (String nam

public class Worker {

    private String name;

    public Worker() {

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

    public int getAge() {

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

    public String getName() {

    @Override
    public String toString() {
