Well just some questions about performance, but i think some of the questions are logical:
– If i use variables with short names will be better/faster to process?
Example: “String s”, will be better than “String superphrase”.
– About the file names, if the file name is short will be faster to access it?
Example: (almost the same) filename.txt or f.txt.
Thanks to all guys, i really like to make my software as better as i can :)

No. Variable names might not even be in your resulting bytecode. In the end of the day variables are mapped to registers/stack operands. Variable name is irrelevant. It’s only for human beings. And they tend to prefer superPhrase over s.
if the file name is short will be faster to access it
No. Files, just like variables, are referenced using special identifiers (e.g. inodes). File name is only needed when opening/locating a file. And it’s several orders of magnitude faster compared to actual file access. This applies equally to Java applications and other OS processes.
