need help with system.out.println....................
Hi, im getting weird results from system.out.println...........
When i run test the result i get its a space then brown like so (with no full stop)
. brown
When i run test2 i get the following
robert
brown
I cant for the life of me understand why this is happening.
Also if i use system.out.print in test i get nothing, both test methods are at the bottom....
