One hex digit represent 4 binary digits. The max value a hex
can have is F (decimal 15) which is 1111 in binary. The way I
approach it is to use base 10 (decimals) as an intermediary between them like this:
F = decimal 15, decimal 15 = 1111 binary
E = decimal 14, decimal 14 = 1110 binary
D = decimal 13, decimal 13 = 1101 binary
So if you have a larger hex number, you just apply this to each
hex digit.
0x4A:
4 = decimal 4 = 0100 binary
A = decimal 10 = 1010 binary
Answer = 0100 1010
0xEC13
E = decimal 14 = 1110 binary
C = decimal 12 = 1100 binary
1 = decimal 1 = 0001 binary
3 = decimal 3 = 0011 binary
Answer = 1110 1100 0001 0011

The Integer.parseInt( String s, int radix ) method can be used to convert a hexadecimal String representation of a number to an int. The Integer.toBinaryString( int i ) method can then be used to convert that int to a binary representation in a String.

Thank you Owen. That was a very clear description on how to do the conversion.
