Fortran is the oldest programming language in existence today, because of this it has a lot of cruft. However, if you put your compiler in standard mode (2003 or 2008 standard) you have a pretty modern language: modules, interfaces, functions that contains functions etc ... You can do OOP in Fortran if you use a modern compiler and stay close to the standard.
Where Java beats hands down Fortran is at the huge ecosystem and libraries available for a variety of domains. Another weak spot for Fortran is that it doesn't stop you to shoot yourself in the foot and you can use implicit types, case insensitivity and globals all over the place.
