HI FRIENDS,
HERE YOU CAN GET SOME IMPORTANT QUESTIONS THAT ARE ASK IN ALL INTERVIEW AND VI-VA.
HERE I COVERED MANY TOPIC WITH DIFFERENT QUESTIONS. THESE QUESTIONS ARE FOR BEGINNER OR PROFESSIONALS.
INTERVIEW QUESTIONS ARE ON TOPIC THAT ARE COVERED IN THIS BLOG AREJAVA, C. C++, SOFTWARE TESTING, SOFTWARE ENGG, NETWORKING ETC.
What are JAVA Byte Codes?
Java bytecode is an intermediate language which is typically compiled from Java.
What is JIT (Just-in-Time) Compilation ?
There are two ways a language can be compiled
a) Compiled Language
b) Interpreted Language
A machine understats only banary language, so fanally a source code has to be compiled in binary format. In compiled way the compiler directly generate the binary file from source code.While in interpreted way it generate the class file which is then run by virtual machine.That means binary file is generated at the run time (compilation is done on need basis) this type of compiltion is called JIT (Just-in-Time) Compilation.
What’s the relation between Classes and Objects?
Class is a defenition , where as object is an instance of a class created.Class is a blue print while Objects are actual objects existing in the real world. Eg: Suppose person is a class- John, Sara.. are objects of class person.
What's singleton class ?
In object-oriented programming, a singleton class is a class that can have only one object (an instance of the class) at a time.
What are Abstract methods ?
An abstract class can have abstract methods. You declare a method abstract by adding the abstract keyword in front of the method declaration.
Adbtract method do not have implementation.
Abstract method should be implemented in the sub class which inherit them.
public abstract class MyAbstractClass {
public abstract void abstractMethod();
}
What’s the difference between 'Abstract' classes and 'Interfaces' ?
1) Absract Class can only be inherited, while interface cannot be. Interface has to be implemented.
2) Abstract class can have implementation ,where as interface cannot implement methods.
