Encapsulation:Binding (or wrapping) code and data together into a single unit is known as encapsulation. A java class is an example of encapsulation. It also protects the integrity of the data – prevents it from being needlessly altered by restricting access to the data, preferably by hiding ...
In this example, we have a parent classTeacherand a child classMathTeacher. In theMathTeacherclass we need not to write the same code which is already present in the present class. Here we have college name, designation and does() method that is common for all the teachers, thus MathTeac...
-The Guide to Java -Interview Questions for Programmers Did you know? In some object-oriented languages (like C++), objects can create copies of themselves. This recursive object creation opens up fascinating possibilities in software design. ...

10. What is diamond problem in case of multiple inheritance? Answer: Let’s understand this with the help of simple example. Let’s assume: Class A has two child classes B and C. Class D has two parent classes B and C. methodCommon() of A is overriden by classes B and C. ...
oops. The idea of compressed oops is raised from the differences between 32bit and 64bit architecture. So we will have a very short review of 64bit architecture and then go deeper into the topic of compressed oops. At the end we will see it all in action with a simple example. ...
