It depends. There is many ways to do that.
All example I will show are to put in the main function, except the last.
The simpliest way to calculate the sum of three numbers is:
System.out.print(3 + 5 + 9);
So, it is really easy.
Other way is to put sum in variable.
int sum = 3 + 5 + 9;
And use System.out.print(sum).
You can also create three separates variables:
int a = 3, b = 5, c = 9;
int sum = a + b + c;
System.out.print(sum);
An other way, to calculate how many numbers you want, is to create a function, under or over the main, it is an algorithm.
public static int sum(int... args)
{
int s = 0;
for(int arg : args)
{
s += arg;
}
return s;
}
With this, you can do simply:
System.out.print(sum(3, 5, 9, -10, 6)); for example in the main function.
Hope I could help you :)
