编程：写一个Worker类，并创建多个Worker对象

public class TestWorker{
    public static void main(String[] args) {
        Worker w = new Worker();
        w.name = "fangfang";
        w.age = 18;
        w.salary = 20000.0;
        System.out.println(w.name+"\t"+w.age+"\t"+w.salary);
        Worker w1 = new Worker("李华",21,12000.0);
        System.out.println(w1.name+"\t"+w1.age+"\t"+w1.salary);
        w1.work(9);        
    }
}
class Worker{
    String name;
    int age;
    double salary;
    public Worker(){}
    public Worker(String name,int age,double salary){
        this.name = name;
        this.age = age;
        this.salary = salary;
    }
    public void work(){}
    public void work(int t){
        System.out.println("工人工作时间");        
    }
}
