Parsing and Formatting a Byte Array into Binary

   

import java.math.BigInteger;

public class Main {
  public static void main(String[] argv) throws Exception {
    byte[] bytes = new byte[] { (byte) 0x12, (byte) 0x0F, (byte) 0xF0 };

    // Create a BigInteger using the byte array
    BigInteger bi = new BigInteger(bytes);

    String s = bi.toString(2); 
    System.out.println(s);

  }
}
