java.math.BigInteger.shiftLeft(int n)

Description Of BigInteger: shiftLeft(int n)

The java.math.BigInteger.shiftLeft(int n) BigInteger whose value is (this << n). The shift distance, n , may be negative, in which case this method performs a right shift. (Computes floor(this * 2ⁿ))

BigInteger.shiftLeft(int n) method returns this << n

Code Example Java BigInteger

import java.math.BigInteger;

public class BigIntegerExam {
 public static void main(String[] args) {
  BigInteger bi1 = new BigInteger("10");

  // perform leftshift operation on bi1 using 2 and -2
  BigInteger bi2 = bi1.shiftLeft(2);
  BigInteger bi3 = bi1.shiftLeft(-2);

  System.out.println(bi2);
  System.out.println(bi3);
 }
}
