2048 Java Implementation of games and 2048 Java Implementation of games

Writing is in a hurry, the function is relatively simple, the interface is ugly, and the number of operation steps should be optimized.

In the end, I still want to write AI, but it seems that it is not that simple. I wrote a few functions about pattern evaluation and I still have to continue learning...

The up, down, and left direction keys are operated.
