Parsing and Formatting a Byte Array into Binary in Java
Set a BigInteger object.
BigInteger one;
Now, create a ByteArray.
byte byteArr[] = new byte[] { 0x1, 0x00, 0x00 }; one = new BigInteger(byteArr);
For Binary, we have used 2 as the toString() method parameter.
String strResult = one.toString(2);
The following is an example −
Example
import java.math.*; public class Demo { public static void main(String[] args) { // BigInteger object BigInteger one; byte byteArr[] = new byte[] { 0x1, 0x00, 0x00 }; one = new BigInteger(byteArr); String strResult = one.toString(2); System.out.println("ByteArray to Binary = "+strResult); } }
Output
ByteArray to Binary = 10000000000000000
