Array Interview Question

-

 Array

=====

We can store multiple values of similar datatypes in a single variable

Similar datatypes

Index based

Index starts from 0 to n-1.

Array syntax

=============

DataType variable [] = new Datatype [Size];


2D Array

==========================

DataType variable [ ] [ ] = new Datatype [size] [size];



DisAdvantages of

------------------

We can store only the similar datatypes

once we fixed the size we cant modified

memory wastage is high


normal enhanced forloop (for each)

==================================

index based value based

condition set        no condition

Chances of error    less chance of error

Method: Set of actions to be performed. 4 Principles of OOPS: Polymorphism Abstraction Inheritance Encapsulation Two Standard notation or coding standards: JAVA: Developed Pascal notation: Camel notation. Pascal Notation: Each word of the first letter should be capital. Eg. J ava T esting. Followed in: project name, class name. Camel Notation: First word of first letter small remaining each word of first letter should be capitol. Eg. j ava T esting C ourse Followed in: object name, variable name, method name. Project-> package-> class-> method -> object Ant : Class a() - m b() - m Object Creation: ClassName objectName= new ClassName(); Ant z=new Ant(); Method Call: objectName.methodName(); z.a(); z.b(); To Create a ...
