# BigInteger shiftRight() Method in Java

prerequisite : BigInteger Basics

The java.math.BigInteger.shiftRight(int n) method returns a BigInteger whose value is (this >> n). The shift distance, n, may be negative, in which case this method performs a left shift. The shiftRight() method will move each digit in a number’s binary representation right by n times and the last bit in the direction of the shift is replaced by 0. This shiftRight() method Computes floor(this / 2^n).

Syntax:

`public BigInteger shiftRight(int n)`

Parameter: The method takes one parameter n of integer type which refers to the shift distance in bits.

Return Value: The method returns the BigInteger after shifting the bits to right by n times.

Exceptions: The method might throws an ArithmeticException if the shift distance is an Integer.MIN_VALUE.

Examples:

```Input: BigInteger = 2300, n = 3
Output: 287
Explanation:
Binary Representation of 2300 = 100011111100
Shift distance, n = 3.
After shifting 100011111100 right 3 times,
Binary Representation becomes 100011111
and Decimal equivalent of 100011111 is 287.

Input: BigInteger = 35000, n = 5
Output: 1093
```

Below program illustrates shiftRight(index) method of BigInteger:

 `// Program to demonstrate shiftRight() ` `// method of BigInteger  ` ` `  `import` `java.math.*; ` ` `  `public` `class` `GFG { ` ` `  `    ``public` `static` `void` `main(String[] args) ` `    ``{ ` ` `  `        ``// Create BigInteger object ` `        ``BigInteger biginteger = ``new` `BigInteger(``"2300"``); ` ` `  `        ``// Create a int i for Shift Distance ` `        ``int` `i = ``3``; ` ` `  `        ``// Call shiftRight() method on bigInteger at index i ` `        ``// store the return value as BigInteger ` `        ``BigInteger changedvalue = biginteger.shiftRight(i); ` ` `  `        ``String result = ``"After applying shiftRight by Shift Distance "` `+ i +  ` `        ``" on "` `+ biginteger + ``" New Value is "` `+ changedvalue; ` ` `  `        ``// Print result ` `        ``System.out.println(result); ` `    ``} ` `} `

Output:

```After applying shiftRight by Shift Distance 3 on 2300 New Value is 287
```
