Constructor in java : >A constructor is a special member method which will be called by the jvm automatically(implicitly)  whenever an object is created for placing placing our own values instead of placing default values. PURPOSE: *the purpose of constructor concept is initialize an object. *Advantages of constructor:  1.constructor Eliminates default values .  2.constructor eliminates in calling the ordinary method explicitly. *Rules/properties of constructor: 1.constructor will be called automatically by the jvm whenever an object is created. 2.the name of constructor must be similar to class name. 3.constructor should not return an return type,even void also.(if we write any return type then it will be    treated as ordinary method). 4.constructor modifier should not be static because constructor will be called each and every time whenever an object is created .java does not contain static constructors. 5.constructor will not be participated i...

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...

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 ...
