My partner and I set an eclipse from scratch with a subtitle ... But neither I nor he can compare files !!
Right-click the file> Compare s> Editing or anything we tried to do to perform the comparison, and it will always be! I get java.lang.nullpointerexception error message and nothing more!
Here is what I get from the magazine
