Java BitSet - flip() Method
The java.util.BitSet.flip() method is used to set each bit from the specified fromIndex (inclusive) to the specified toIndex (exclusive) to the complement of its current value in the given BitSet.
Syntax
public void flip(int fromIndex, int toIndex)
Parameters
fromIndex |
Specify the index of the first bit to flip. |
toIndex |
Specify the index after the last bit to flip. |
Return Value
void type.
Exception
Throws IndexOutOfBoundsException, if fromIndex is negative, or toIndex is negative, or fromIndex is larger than toIndex.
Example:
In the example below, the java.util.BitSet.flip() method is used to flip the bit for a range of index in the given BitSet.
import java.util.*;
public class MyClass {
public static void main(String[] args) {
//creating a BitSet
BitSet BSet = new BitSet();
//populating the BitSet
BSet.set(10);
BSet.set(20);
BSet.set(30);
BSet.set(40);
BSet.set(50);
//printing the BitSet
System.out.println("BSet contains: " + BSet);
//flipping the bit for range [27, 33)
BSet.flip(27, 33);
//printing the BitSet
System.out.println("BSet contains: " + BSet);
}
}
The output of the above code will be:
BSet contains: {10, 20, 30, 40, 50}
BSet contains: {10, 20, 27, 28, 29, 31, 32, 40, 50}
