Thread: I can't clone an object

Sorry for a possibly stupid question in advance: I am just a beginner and just study Java. The compiler gives clonenotsupportedexception for the House house2 = (House)house1.clone() part of the code. I do not understand why as the House class implements the Cloneable interface. Thank you in advance for your hints and advice.

public class House implements Cloneable, Comparable {
    private int id;
    private double area;
    private java.util.Date whenBuilt;
 
    public House(int id, double area) {
        this.id = id;
        this.area = area;
        whenBuilt = new java.util.Date();
    }
 
    public double getId() {
        return id;
    }
 
    public double getArea() {
        return area;
    }
 
    public java.util.Date getWhenBuilt() {
        return whenBuilt;
    }
 
    /** Override the protected clone method defined in the Object
     class, and strengthen its accessibility */
    public Object clone() throws CloneNotSupportedException {
        return super.clone();
    }
 
    /** Implement the compareTo method defined in Comparable */
    public int compareTo(Object o) {
        if (area > ((House)o).area)
            return 1;
        else if (area < ((House)o).area)
            return -1;
        else
            return 0;
    }
}
class Implement
{
 
 
    public static void main (String [] args)
 
    {
        House house1 = new House(1, 1750.50);
        House house2 = (House)house1.clone();
    }
}

use try and catch Exception instead of the throwing one. I tried your code with try and catch and it worked. So use
try
{
}catch(Exception e)
{
return this;
}

this should work

Norm and myjava! Thank you very much for your help! I was just inattentive and didn't read carefully enough what the compiler really told me. May be it was my greatest mistake. And now the answer seems so evident to me!
