Create Converter.java

This is a task from my assistant practical, because I upload wrong file for my Journal xD. Actually this is a bonus task. And if I finish it, I will get perfect score for my last practical work. Unfortunately I can only submit half of it on the deadline ( I got lot of another task --' ). 

And here, the algorithm for Converter from Binary,Octal,Decimal,Hexadecimal to Binary,Octal,Decimal,Hexadecimal.

#note : I'm not using converter library on java, well.. this can improve your logic on thinking an algorithm =)) enjoy!
