Possible Array Declarations and 2-D Arrays.

In this article,Possible Array Declarations and 2-D Arrays are explained in detail with examples.

In java we can declare an one dimensional arrays in possible ways.

int a[];

int []a;

int...a; //used only as varargs in methods

          // as last parameter.

Command line arguments

The main method takes string arrays as the input parameter.Such parameters could be passed as arguments while executing the Java program.

Syntax

Matrix addition,subtraction and Wrapper Classes.

In this article,Matrix addition,subtraction and Wrapper Classes are explained in detail with examples.

To perform these operations, the necessary and sufficient condition are both the matrices should be of same order because the operation is performed on corresponding elements from both the matrices.

Ex

//program related to Matrix addition,subtraction and Wrapper Classes-add,subtraction of a matrix.

class MatrixAddSub

{

public static void main(String args[])

{

int a[][]=new int[2][2];

int b[][]=new int[2][2];

Native methods are those methods whose implementation is done in other languages like C and C++.

The following methods are native methods in the object class. (From topic Object Class and Constructors in Java)

Constructor and Notations in Java.

In this article,Constructor and Notations in Java are explained in detail with examples.
Like methods, Constructors can also take parameters, which acts like input values to the constructor.

Based on this, constructors are divided into two types.
