BigInteger shiftLeft() in Java

shiftLeft(): This method is available in java.math.BigInteger class of Java.

Syntax:

BigInteger java.math.BigInteger.shiftLeft(int n)

This method takes one argument of type int as its parameter. This method returns a 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).).

Parameters: One parameter is required for this method.

n: shift distance, in bits.

Returns: this << n.

For Example:

BigInteger bigInteger = new BigInteger("1234") 

int n = 3

bigInteger.shiftLeft(n) = > It returns 9872.

Approach

Java

import java.math.BigInteger;

public class BigIntegershiftLeft {
    public static void main(String[] args) {

        BigInteger bigInteger = new BigInteger("1234");
        int n = 3;
        System.out.println(bigInteger.shiftLeft(n));
    }
}

Output:

9872
