用Java该如何做一下这个内容呢

创建一个Collection集合对象，在该容器中增加三个工人，基本信息如下:
姓名 年龄 工资
zhang3 18 3000
li4 25 3500
wang5 22 3200

public class zz {
    private String name;
    private int age;
    private BigDecimal salary;
    public String getName() {
        return name;
    }
    public int getAge() {
        return age;
    }
    public BigDecimal getSalary() {
        return salary;
    }
    public void setName(String name) {
        this.name = name;
    }
    public void setAge(int age) {
        this.age = age;
    }
    public void setSalary(BigDecimal salary) {
        this.salary = salary;
    }
    public zz(String name,int age,BigDecimal salary){
        this.name=name;
        this.age=age;
        this.salary=salary;
    }
    public static void main(String[] args) {
        Collection<zz> collection=new Vector<zz>();
        collection.add(new zz("zhang3",18,new BigDecimal(3000)));
        collection.add(new zz("li4",25,new BigDecimal(3500)));
        collection.add(new zz("wang5",22,new BigDecimal(3200)));
        for (zz collectionZz:collection){
            System.out.println(collectionZz.getName()+"\t"+collectionZz.getAge()+"\t"+collectionZz.getSalary());
        }
    }
         }
