In Pictures: 15 things we hate about Java

Slow startup times, null pointers, security flaws -- Java's ongoing success leaves plenty to complain about

Endless checking for null pointers Is there anything to this complaint? Let me check if it's null before typing any more. Seems fine. Now let me check if my keyboard is still here and hasn't been replaced by something null. It's still here. Now I'll move my fingers and tell you why null testing is a pain.

Java requires endless if statements to test whether variables have ended up null; otherwise entire threads crash with NullPointerExceptions. Smartass developers say it's my fault for not checking the input at the beginning, but that's often not possible when creating libraries. If someone picks up this class file in the future, you better check all the variables yet again, because you have no idea how they will reuse it.

STYLISTIC Q702

First impression on unpacking the Q702 test unit was the solid feel and clean, minimalist styling.

STYLISTIC Q572

For work use, Microsoft Word and Excel programs pre-installed on the device are adequate for preparing short documents.

LIFEBOOK UH574

The Fujitsu LifeBook UH574 allowed for great mobility without being obnoxiously heavy or clunky. Its twelve hours of battery life did not disappoint.

STYLISTIC Q702

The screen was particularly good. It is bright and visible from most angles, however heat is an issue, particularly around the Windows button on the front, and on the back where the battery housing is located.

STYLISTIC Q702

My first impression after unboxing the Q702 is that it is a nice looking unit. Styling is somewhat minimalist but very effective. The tablet part, once detached, has a nice weight, and no buttons or switches are located in awkward or intrusive positions.
