        Today i am going to show you how to add two numbers by java on console. go through the code below:
public class addition
public static void main(String args[])
float a,b,c;
DataInputStream input=new DataInputStream(;
System.out.println("enter two numbers for addition");
 System.out.println("the total is "+c);
Explanation :-

import :- first line of code, import is a keyword for import packages(a package is collection of many inbuilt classes and functionality can use in our program) and .* means all the classes from the package will be imported. :- is a package, contains the classes that handle fundamental input and output operations in Java.
float :- datatype represents real a,b,c three variable defined.
DataInputStream :- defined in package This class has method for reading data from the console. :- represents that we want to read from standard input system i.e. from keyboard.
Float.parse :- typecasting(convert the input stream in float).
input.readLine() :- the readLine method of class DataInputStream allows us to read a string from keyword.

c = a + b performs addition and assign results to c and we can print results.

We can speed the process in visual manner, no need IO classes in Netbeans, there is a visual editor as Visual Studio for C ASP.NET, clicking on button trigger the event as ASP.NET; so no need to reuse IO classes for teachers :)
