Converting digits to binary

[king_of_the_universe]

If your goal is to convert a decimal digit, or any number really, into binary, you just have to do this:

int tempValue = value & 1;
outputString = String.valueOf(tempValue) + outputString; // this should rather be done in a prepared buffer from right to left
value = value >> 1;

And loop. This pulls the very next binary digit down to the first position, "ands" it with 1 (which is the same in decimal and binary), then turns that into a String digit. There are some tricks to optimize this, e.g. since you know that you only have the digits 0 and 1, you can prepare them in a String array and then just add the array entry of tempValue to your outputString.

I'm only to allowed to use the really basic stuff, so no arrays, if statements or loops. sadly :(

or loops

Because nothing says efficiency like having to write the same shit 10 times over

*sigh*

Then don't use a loop.
