Polymorphism is the concept where an object behaves differently in different situations. There are two types of polymorphism - compile time polymorphism and runtime polymorphism. Compile-time polymorphism is achieved bymethod overloading. For example, we can have a class as below. public class Circl...
Here SubClassB inherited the methodfoo()fromSuperClassA. Polymorphism:Polymorphism means taking many forms, where ‘poly’ means many and 'morph' means forms. Polymorphism allows you define one interface or method and have multiple implementations. In Java, there are two types of polymorphism: comp...

As we expected the heap size increased. The majority of heap is occupied by two types of objects, linked list nodes and integers. There are more than 2 million integers that in the compressed oops version required 32 million bytes and in non compressed oops 48 million bytes. With a simple...
There are three types of OOPS: Poor OOPS True OOPS Pure OOPS C++ is example of poor OOPS, actually in C++, we can access private data member outside the class using pointers and friend function. Java and C# are example of True oops. ...
