How to generate random positive and negative numbers in Java




I am trying to generate random integers over the range (-32768, 32767) of the primitive data type short. The java Random object only generates positive numbers. How would I go about randomly creating numbers on that interval? Thanks.


Answer



You random on (0, 32767+32768) then subtract by 32768
