WAP to add two numbers by just assigning values(J2SE).

J2SE Programming

Now I am going to write a program which adds two numbers.
For this i just want to know about addition operator and two inputs.
As we know, there is one operator known as plus(+) operator can be used to add two inputs.
Now the problem is how to get input for adding numbers.

 There are three ways to get input as follows:-

1. One way is just by assigning values.
2. Second way is by User input during Run-time.
3. Third way is using Command-Line arguments.

Here we are using First way i.e. by Assigning values.
Other ways will be discussed Later.

class Addition                               {                                           //Main Function                                        public static void main(String[] args)                                       {                                           Addition a1=new Addition();                                           int a=a1.add(10,20);                                           System.out.println(Sum is : +a);                                       }                                //Function to add two numbers                                        public int add(int a,int b)                                       {                                          int c=0;                                          c=a+b;                                          return c;                                       }                               }

Now save it as Addition.java
Compile it using "javac Addition.java" Command in CMD
After compilation Run it using command "java Addition" in CMD
