Java red envelopes

Red envelopes using Java implementation of the function.

　　structure:

　　　　package redPocket 　　　

　　　　　　User.java　　　　　　

　　　　　　Manager.java

　　　　　　Member.java

　　　　　　Demo.java

　　Ideas:

　　　　Manager and Member class inherits User, Manager class implements the functions of the main group of red envelopes, Member class implements the group members received a red envelope function. Demo test code.

　　Code:

　　　　

package redPocket;

public class User {
    private String name;
    private float money;

    public User() {
    }

    public User(String name, float money) {
        this.name = name;
        this.money = money;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public float getMoney() {
        return money;
    }

    public void setMoney(float money) {
        this.money = money;

    @Override
