In this post, we will discuss Serialization and deserialization of Java objects of Java objects using Jackson library by converting Java Objects into their JSON representation and then JSON to an equivalent Java object.
In this post, we will discuss how to copy objects in Java using copy constructor. We will also cover Factory method approach that does the same.
In this post, we will discuss about shallow copy and deep copy in java in detail with examples.
In this post, we will see how to declare and initialize jagged array in Java.
In this post, we will discuss how to copy an object in Java using clone() method in Object class and one provided by Apache Commons Lang. We will also discuss about shallow copy and deep copy in detail.
