問題：
I have a Java method in which I'm summing a set of numbers.我有一個Java方法，其中對一組數字求和。 However, I want any negatives numbers to be treated as positives.但是，我希望將任何負數都視爲正數。 So (1)+(2)+(1)+(-1) should equal 5.所以（1）+（2）+（1）+（-1）應該等於5。
I'm sure there is very easy way of doing this - I just don't know how.我敢肯定有很簡單的方法可以做到-我只是不知道怎麼做。
