// Get a byte array
byte[] bytes = new byte[]{(byte)0x12, (byte)0x0F, (byte)0xF0};
// Create a BigInteger using the byte array
BigInteger bi = new BigInteger(bytes);
// Format to binary
String s = bi.toString(2); // 100100000111111110000
// Format to octal
s = bi.toString(8); // 4407760
// Format to decimal
s = bi.toString(); // 1183728
// Format to hexadecimal
s = bi.toString(16); // 120ff0
if (s.length() % 2 != 0) {
// Pad with 0
s = "0"+s;
}
// Parse binary string
bi = new BigInteger("1001000001111111100 00", 2);
// Parse octal string
bi = new BigInteger("4407760", 8);
// Parse decimal string
bi = new BigInteger("1183728");
// Parse hexadecimal string
bi = new BigInteger("120ff0", 16);
// Get byte array
bytes = bi.toByteArray();
