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;
}
}

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;
}
}
System.out.println("请选择1-2");
这里你选择的是1还是2啊？
System.out.println(houseList[i]);这哪能输出内容啊
你应该在house类里封装一个print函数，输出其内容，然后System.out.println(houseList[i]);改为 houseList[i].print();就行了
