Left shift bit value on BigInteger

BigInteger shiftLeft(int n) Returns a BigInteger whose value is (this << n).

import java.math.BigInteger;
/*  j a  va 2s.c  om*/
public class Main {
  public static void main(String[] argv) throws Exception {
    byte[] bytes = new byte[] { 0x1, 0x00, 0x00 }; 
    BigInteger bi = new BigInteger(bytes);
    bi = bi.shiftLeft(3);
    System.out.println(bi);
  }
}

The output:

Right shift bit on BigInteger

BigInteger shiftRight(int n) returns a BigInteger whose value is (this >> n).

import java.math.BigInteger;
//  j a  va 2s.co  m
public class Main {
  public static void main(String[] argv) throws Exception {
    byte[] bytes = new byte[] { 0x1, 0x00, 0x00 }; 
    BigInteger bi = new BigInteger(bytes);
    bi = bi.shiftRight(1);
    System.out.println(bi);
  }
}
