Addition of two Numbers in Class
In this program we will learn how to calculate the sum of any two
number. Java is a object oriented programming language in which uses of
class consists of a collection of type of encapsulation instance variables and type of methods. We are going to use in
this program of class method. Class is a
cohesive package that consist of a particular values at compile time. The
class is describe the rules by which object are referred to as instance
value.
Description this program
Here in this program we are going to use addition
of two number. First of all, we have to define class named "SumExample".
We are going to define two integer type values in the class method.
After that we are going to create buffer reader object for read the text
charactor- input stream and buffer is also provide for the efficient read of
charactor values. As in this program we are going to insert certain instruction
by creating buffer reader class. it is necessary to use 'try' and 'catch'. Now we are going to create parseInt method for read text line.
After that we have to create object and return the integer
type values. So output will be display by
using "sum= sum1.x+sum1.y".
Here is the code of this program
import java.io.*;
public class SumExample{
public int x;
public int y;
public static void main(String args[]){
try {
SumExample sum1= new SumExample();
int sum;
BufferedReader object= new BufferedReader (new InputStreamReader(System.in));
System.out.println("Enter number:");
System.out.print("Enter number x:="+ "");
sum1.x=Integer.parseInt(object.readLine());
System.out.print("Enter number y:="+ "");
sum1.y=Integer.parseInt(object.readLine());
sum= sum1.x+sum1.y;
System.out.println("Sum is:"+ sum);
}
catch(Exception e){}
}
}
