为什么没有输出结果？求解答

Question

问题是只输出：MyProject.Attribute.House@6f94fa3e，没有输出用户输入的数据

package MyProject.Attribute;

public class House {
    private int houseId;
    private String nameOfLady;
    private String address;
    private double rent;
    private String phone;
    //构造方法
    public House(int houseId,String nameOfLady, String address, double rent, String phone) {
        setNameOfLady(nameOfLady);
        setAddress(address);
        setRent(rent);
        setPhone(phone);
        setHouseId(houseId);
    }
    //封装
    public String getNameOfLady() {
        return nameOfLady;
    }
    public void setNameOfLady(String nameOfLady) {
        this.nameOfLady = nameOfLady;
    }
    public String getAddress() {
        return address;
    }
    public void setAddress(String address) {
        this.address = address;
    }
    public double getRent() {
        return rent;
    }
    public void setRent(double rent) {
        this.rent = rent;
    }
    public String getPhone() {
        return phone;
    }
    public void setPhone(String phone) {
        this.phone = phone;
    }
    public int getHouseId() {
        return houseId;
    }
    public void setHouseId(int houseId) {
        this.houseId = houseId;
    }
}

Answer 1

你输出的是地址，不是对象中的数据。

House类中需要重写toString方法。

House {
    private int houseId;
    private String nameOfLady;
    private String address;
    private double rent;
    private String phone;
    @Override
    public String toString(){
      return "nameOfLady="+ nameOfLady+",address="+address+",rent="+rent+",phone="+phone;
    }
}
