I have a Java method in which I'm summing a set of numbers. However, I want any negatives numbers to be treated as positives. So (1)+(2)+(1)+(-1) should equal 5.
I'm sure there is very easy way of doing this - I just don't know how.

Just call Math.abs. For example:
int x = Math.abs(-5);
Which will set x
to 5
.
Note that if you pass Integer.MIN_VALUE
, the same value (still negative) will be returned, as the range of int
does not allow the positive equivalent to be represented.
