Is there a way to add multiple Ints together?

Question

How do I add Ints or Floats together in Java(or BlueJ)? I mean not that:

x=2;
y=3;
System.out.println(y+x);

and then comes 5 out, I mean rather like this:

x=2;
y=3;
c=y+x;
System.out.println(c);

And here should come out 32. Not adding like in Math, rather like combining these things in one new variable. Thanks a lot in advance!

There are at least two and probably more ways to interpret this question. What, *specifically*, do you expect in `c`? A string? An `int` with the value thirty-two? An `int` in a superposition of the values 3 and 2? (Not going to happen on consumer hardware and an even vaguely standard JVM.) An `int` array with 3 and 2 in it? — T.J. Crowder, Jun 12 '18 at 14:17
What you want is not addition of mathematical `int` values but rather interpreting the values as `String`s and then using *string concatenation*. So the steps are: transform your values to `String`s and then use *string concatenation*. After that transform back to an `int` value. — Zabuzard, Jun 12 '18 at 14:21

Concat your number with a String:

String c = "" + x + y;

This is the correct answer, I don't get the downvotes. – Andrea Jun 12 '18 at 14:18
Its not clear from the question but I think OP also wants to get the result back as `int` again. So you may add `Integer.parseInt(...)`. – Zabuzard Jun 12 '18 at 14:22
