Explain method Overriding and Method Overloading in Java. What do you understand about the final class in Java? The advantages of OOP include reusability, flexibility, and modular development, which improves output and makes the design process more stable. Because of the modularity, Java OOP allow...
In method overriding,method resolution(to execute which method) is done by the JVM based on the type of the object. Hence this concept is also known asrun-time polymorphism. publicclassParent{publicvoiddoSomething(intx){System.out.println("Parent Class int Method");}}publicclassChildextendsPare...

() method from java.lang.Object, the finalize() method is called by garbage collector when it determines no more references to the object exists. In Java, it is good idea to explicitly assign null into a variable when no more in use. I Java on calling System.gc() and Runtime.gc(),...
Why doesn't method overriding work as I expect it? Coping With Legacy What happens when I mix generic and non-generic code? Should I re-engineer all my existing classes and generify them? How do I generify an existing non-generic type or method?
