What is mean by software?

A Software is a collection of programs which are made for performing some specific operation.
    According to industry standard software are classified into 3 types they are
1.System software
2.Application software
3.Internet software

1.System software:
                            there are 3 aims which are
a]Developing the functionality of Hardware devices(driver developement).
     ex:printer scanner etc.

b]Developing Real time operating system(WinOS,Unix,Linux,MACOS).
      in order to fullfill system software we use following languages
     ex:c,ALP.

2Application Software:
                  aim is to develope software for organization.   


It is basic now we see OOPS concepts
1]class
2]Object
3]Data Encapsulation
4]Data Abstraction
5]Inheritance
6]Polymorphism
7]Dynamic Binding
8Message passing

1]class:
   *the purpose of class concept is to develope user defined datatype.
    *in order to use class concepts for development of userdefined datatype we use keyword called 'class '.

Addition or Sum of 2x2 matrix using Arrays in java

We know that arrays are different types, as usual one dimensional array, two dimensional array, three and multi (mxn) dimensional arrays. In two dimensional arrays we need 2x2 array. A 2x2 matrix is a rectangular often square array of numbers having 2 columns and 2 rows, or expressions which can be evaluated to numbers. The dimensions m x n refer to the number of rows (m) and columns (n) respectively. We can declare the one dimensional array as: int[] myArray = {0,1,2,3}; and two dimensional array looks like this: int[][] myArray = { {0,1,2,3}, {3,2,1,0}, {3,5,6,1}, {3,8,3,4} };        this array size is 4X4. Here in our program we are using 2X2 array only. Let us take two arrays named as A(2X2) and B(2X2), then add these two arrays. The resultant array(matrix) named as C(2X2). A general formula shown below notice that the indices match for the elements that combine, and that matrix addition and subtraction is commutative; e.g (A + B = B + A...
