In the example given below, we are creating an object of the class using deserialization and this method is more about serialization and deserialization than creating an object. Firstly make sure that Class of which you want to create an object must be a serializabel to do so implement a Ser...
In this tutorial, we will learnhow to create an object in Javawith the help of examples. We know that everything is an object in Java. A class is a model or user-defined blueprint for creating objects. It encapsulates the relevant data members and methods (behaviors) that an object of ...
When we want to copy an object in Java, there are two possibilities that we need to consider,a shallow copy and a deep copy. For the shallow copy approach, we only copy field values, therefore the copy might be dependant on the original object. In the deep copy approach, we make sure...
Rules to create immutable class: In order to make a Java class immutable, follow these rules. Do not implement setter methods (known as mutators) that can modify the state of the object. Declare all fields (data members) private and final. private, so that they cannot be accessed outside...
object only uses primitive fields. We can make a deep copy of an object by using the Cloneable() interface and overriding the clone() method. Copy constructors are an easier and more flexible way of performing a deep copy. We can also use Serialization but we need to remember that its ...
