Thread: A simple java program sum of n number

Hey guy i am in big problem.Actually i don't having much knowledge about Java.I am familiar only with Java.I don't have much knowledge about programing.So guys help me in writing a program on to above topic "A simple Java programing sum of n number using class,object and methods."

So, where are you stuck ?
I mean where is the difficulty ?
If you show the code you have developed then we can help you, I don't think we are here to complete your homework , we can clear doubts and you should try yourself
Online tutorial for java can be found @ Java Developer Tutorials and Online Training
Also,the abstract of programming is similar to C++

It’s a visual, flexible, meaningful, and systematic approach to effective and efficient learning through the use of an active, cognitive, inquiry-based, and constructive process.

i hope this will help u
****** Java Program To Print Sum Of 'n' Number ******/

class Add
{
public static void main (String args[])
{
int n = 15;
int sum = 0;
for(int i = n;i>=0;i--)
sum = sum + i;
System.out.println("Sum = "+ sum);
}
}

/*************** OUTPUT *************
* *
* Sum = 120 */

An alternative solution to the first problem with summing up to n..

int n = 50; //Just representing the user input.
for (int i = 0; i < 1; i++) {
int sum = (n * (n + 1)) / 2;
}

System.out.println(sum);

It's using a loop and that was the requirement, right?!

I notice it's in your code, the formula of an arithmetic sum. It's very useful in programming and math so remember it
