Java developer Interview Questions in United States

what sort of questions?

Release your anger. Tell us he questions.

I want to know that all the round has been taken on the same day or they called you later for next round

Inheritance means readability of existence function Interface does not have body but it has method signature Multiple inheritance means exhibiting the properties of multiple functions

Getting the properties n behaviors of another class

Inheritance in Java is a mechanism in which one object acquires all the properties and behaviors of a parent object.

Yes. Mentioned that ehCache. Didn't go into detail.

Infinispan.

Method overloading is when you have two or more methods in a class with have the same method name but different parameters or even different return type. e.g public int sum (int a , int b){ return a + b; } public int sum (int a, int b, int c){ return sum (sum ( a, b), c); }

Method overriding on the other hand is declaring a method in subclass which is already present in parent class. The subclass can then provide an implementation. An example is ovveriding the toString() or equals() methods from the Object superclass and then providing specific implementation of the methods in your class. Second difference is that Overloading happens at compile-time while Overriding happens at runtime: The binding of overloaded method call to its definition has happens at compile-time however binding of overridden method call to its definition happens at runtime.

Java is − Object Oriented − In Java, everything is an Object. Java can be easily extended since it is based on the Object model. Platform Independent − Unlike many other programming languages including C and C++, when Java is compiled, it is not compiled into platform specific machine, rather into platform independent byte code. This byte code is distributed over the web and interpreted by the Virtual Machine (JVM) on whichever platform it is being run on. Simple − Java is designed to be easy to learn. If you understand the basic concept of OOP Java, it would be easy to master. Secure − With Java's secure feature it enables to develop virus-free, tamper-free systems. Authentication techniques are based on public-key encryption.

I think you should mention and explain APIE = Abstraction , Polymorphism, Inheritance and Encapsulation

A java Package is a group of similar type of classes , interfaces and sub-packages.

a package is a namespace that organized a set of related classes and interfaces.

I just said something along the lines of it being a new and exciting place to work
