how to convert decimal to binary? && binary to decimal?

HELP guyz?! please?!!

Everything in the computer is in binary, I assume that its the representation of that binary data as Strings that you are talking about.

What data type do you have as input and what type do you want as output.
For example if the input is an int and the output is a String, see the Integer class for methods to create Strings from ints.
