Question 1

What is static polymorphism

Answer 1

implement multiple methods within the same class that use the same name but a different set of parameters.

Question 2

What is the process of static polymorphism referred as

Answer 2

is called method overloading

Question 3

What functions does the JVM provide

Answer 3

JVM is also platform dependent and provides core java functions like memory management, garbage collection, security etc.

Question 4

what does JRE stand for

Answer 4

java run environment

Question 5

What is dynamic polymorphism

Answer 5

Within an inheritance hierarchy, a subclass can override a method of its superclass. That enables the developer of the subclass to customize or completely replace the behavior of that method.
Both methods, implemented by the super- and subclass, share the same name and parameters but provide different functionality.

Question 6

what does JVM stand for

Answer 6

java virtual machine

Question 7

What time does static polymorphism run?

Answer 7

compile-time

Question 8

what is the JDK

Answer 8

Software Development environment used for developing java apps and applets. provides all the tools, executables and binaries required to compile, debug and execute a Java Program.

Question 9

What time does dynamic polymorphism run?

Answer 9

run-time

Question 10

what does JDK stand for

Question 11

What is a JVM

Answer 11

JVM is a engine that provides runtime environment to drive the Java Code or applications. It converts Java bytecode into machines language.

Question 12

what contains the JVM

Answer 12

JRE and JDK

Question 13

Overriding

Answer 13

Overriding means having two methods with the same method name and parameters (i.e., method signature). One of the methods is in the parent class and the other is in the child class. Overriding allows a child class to provide a specific implementation of a method that is already provided its parent class.

Question 14

What is the JRE

Planning – 
Requirements – 
Design and prototype – 
software development – 
testing – 
deployment – 
operations and maintenance

Question 16

overloading

Answer 16

Overloading occurs when two or more methods in one class have the same method name but different parameters.

Question 17

what is Java inheritance

Answer 17

Sub and super classes (parent and child)
Mechanism in which one object acquires all the properties and behaviors of a parent object. Used for method Overriding (so runtime polymorphism can be achieved) and For Code Reusability.
class Subclass-name extends Superclass-name

Question 18

what time does overriding occur

Answer 18

Overriding is a run-time concept

Question 19

what is Java Composition

Answer 19

Association is relation between two separate classes which establishes through their Objects. Association can be one-to-one, one-to-many, many-to-one, many-to-many.
In Object-Oriented programming, an Object communicates to other Object to use functionality and services provided by that object. Composition and Aggregation are the two forms of association.
