java.math.BigInteger.setBit(int n)

Description Of BigInteger: setBit(int n)

The java.math.BigInteger.setBit(int n) returns a BigInteger whose value is equivalent to this BigInteger with the designated bit set. (Computes (this | (1<<n)))

BigInteger.setBit(int n) method returns this | (1<<n)

Code Example Java BigInteger

import java.math.BigInteger;

public class BigIntegerExam {
 public static void main(String[] args) {
  BigInteger bi1 = new BigInteger("4");

  BigInteger bi2 = bi1.setBit(3);

  System.out.println(bi2); // output 12
 }
}
