Clear a bit in a BigInteger in Java
To clear a bit in a BigInteger in Java, use the clearBit() method. It returns a BigInteger whose value is equivalent to this BigInteger with the designated bit cleared.
Example
import java.math.*;
public class BigIntegerDemo {
public static void main(String[] args) {
BigInteger one, two;
one = new BigInteger("7");
two = one.clearBit(2);
System.out.println("Result: " +two);
}
}Output
Result: 3
Let us see another example.
Example
import java.math.*;
public class Demo {
public static void main(String[] args) {
BigInteger bi1, bi2;
bi1 = new BigInteger("8");
bi2 = bi1.clearBit(2);
String str = "Clearbit operation on " +bi1+ " at index 2 gives " +bi2;
System.out.println( str );
}
}Output
Clearbit operation on 8 at index 2 gives 8
