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...

In this example, we have a list of integers that we want to sort in ascending order. We use theCollections.sort()method to sort the list, and then print the sorted list to the console. The output shows the list sorted in ascending order. This is a basic way to sort a list in Jav...
To solve this problem we use Deep Copy. A shallow copy and a deep copy will give the same results if the 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 ...
Java object cloningusingcopy constructorsanddefensive copy methodscertainly have some advantages but we have to explicitly write some code to achieve deep cloning in all these approaches. And still, there are chances that we might miss something and do not get deeply cloned object. ...
This document describes what you need to do in order to integrate your provider into Java SE so that algorithms and other services can be found when Java Security API clients request them. Who Should Read This Document Programmers who only need to use the Java Security APIs (see Core Classes...

2. To store data temporarily in Java application, we require to create an object. The object provides temporary storage for our data. 3. In Java, By creating an object, we can call the members of one class from another class. It is useful when we need to use common code in every cla...
