Conversion from string to binary string in Java [duplicate]

Question

I have hexadecimal string of length 80bits like "12345ABCDEF78E9CD741" and need to convert into binary string.

I tried the following code String Skey = "12345ABCDEF78E9CD741"; int i = Integer.parseInt(Skey, 16); String bin = Integer.toBinaryString(i);

But the integer cant hold 80 bits. So how this can be done in java.

BigInteger bigint = new BigInteger("12345ABCDEF78E9CD741", 16);
System.out.println(bigint.toString(2));

Output:

10010001101000101101010111100110111101111011110001110100111001101011101000001
