How do I copy an object in Java Basic Object Copying in Java. Let us Assume an object obj. Java-Serialization-1024x518.png' alt='Java Serialized Object Http Post' title='Java Serialized Object Http Post' />Obj. Obj. 2. shallow copying shallow copying creates a new instance of the same class and copies all the fields to the new instance and returns it. Object class provides a clone method and provides support for the shallow copying. Deep copying A deep copy occurs when an object is copied along with the objects to which it refers. Below image shows obj. Not only has obj. We can use Java Object Serialization to make a deep copy. Unfortunately, this approach has some problems toodetailed examples. Possible Problems clone is tricky to implement correctly. Its better to use Defensive copying, copy constructorsas egaga reply or static factory methods. If you have an object, that you know has a public clone method, but you dont know the type of the object at compile time, then you have problem. Java has an interface called Cloneable. In practice, we should implement this interface if we want to make an object Cloneable. Object. clone is protected, so we must override it with a public method in order for it to be accessible. Another problem arises when we try deep copying of a complex object. Assume that the clone method of all member object variables also does deep copy, this is too risky of an assumption. You must control the code in all classes. For example org. apache. Serialization. Utils will have method for Deep clone using serializationSource. If we need to clone Bean then there are couple of utility methods in org. Source. clone. Bean will Clone a bean based on the available property getters and setters, even if the bean class itself does not implement Cloneable. Properties will Copy property values from the origin bean to the destination bean for all cases where the property names are the same. In java serialization class Mp3player extends ElectronicDevice implements Serializable in this code super class electronicdevice is not implemented serializable. Basic Object Copying in Java. Let us Assume an object obj1, that contains two objects, containedObj1 and containedObj2.
