## Description

On this document we will be showing a java example on how to use the shiftRight(int n) method of BigInteger Class. Basically this method returns a BigInteger whose value is (this >> n). Sign extension is performed. The shift distance, n, may be negative, in which case this method performs a left shift. (Computes floor(this / 2n).)

Let’s take a for example a BigInteger `12` which is equivalent to binary `1100`. So if we have a value `n=1`, then the binary `1100` shifted to the right by `1` would become `110`. The equivalent of `110` is `12` which be the returned value of the method `shiftRight()`.

Notes:

## Method Syntax

public BigInteger shiftRight(int n)

## Method Argument

Data Type Parameter Description
int n index of bit to shift.

## Method Returns

The flipBit() method `this >> n`

## Compatibility

Requires Java 1.1 and up

## Java BigInteger shiftRight(int n) Example

Below is a java code demonstrates the use of shiftRight(int n) method of BigInteger class. The example presented might be simple however it shows the behavior of the shiftRight(int n) method.

```package com.javatutorialhq.java.examples;

import java.math.BigInteger;
import java.util.Scanner;

/*
* A java example source code to demonstrate
* the use of shiftRight(int n) method of BigInteger class
*/

public class BigIntegerShiftRightExample {

public static void main(String[] args) {

// initialize a BigInteger object
BigInteger val1 = new BigInteger("12");
/*
* Note: 17 in binary is 10001
*/

// get user input
System.out.print("Enter the shift distance:");
Scanner s = new Scanner(System.in);
String input = s.nextLine();
s.close();

/*
* convert the input to Integer unboxing feature will be used to
* transform Integer to primitive int
*/
Integer inputBitNumber = Integer.parseInt(input);

// get the new BigInteger result after shifting to the right
BigInteger result = val1.shiftRight(inputBitNumber);
System.out.println("Result of the operation:" + result);

}

}```

This example is a lot simpler than it looks. The first part is the declaration of a BigInteger. User are then asked to provide the shift distance. We then shifted the BigInteger object to the right with the specified shift distance. Result is printed at the end.
