The method clone() from object is not visible?

Question

Question:

package GoodQuestions;
public class MyClass {  
    MyClass() throws CloneNotSupportedException {
        try {
            throw new CloneNotSuppo         


        

Answer 1

You just have to make MyClass implement Cloneable interface. No need to provode implementation for clone().

Answer 2

Object.clone() method has protected access, meaning it's visible to sub-classes and classes in the same package.

It's good to have a copy constructor for manually copying the object.

/**
    Deep copy all the information from other to this
*/
public MyClass (MyClass  other) {
     this.id = other.id;
}
