There are two variants of flip() method. This article depicts about all of them as follows:
1. flip(int value) : This method removes the value specified in the argument.
public void flip(int value) Parameters : value : the value to flip. Return ValueThis method does not return a value.
// Java code to demonstrate the// working of flip(int value) in Bitset import java.util.*; public class Flip1 { public static void main(String[] args) { // declaring bitset BitSet bset = new BitSet(6); // assigning values to bset bset.set(0); bset.set(1); bset.set(2); bset.set(3); // printing the original set System.out.println("The original bitset is : " + bset); // using flip() to remove 2 bset.flip(2); // printing final bitset // 2 is removed System.out.println("The flipped bitset is : " + bset); }} |
Output:
The original bitset is : {0, 1, 2, 3}
The flipped bitset is : {0, 1, 3}
2. flip(int fromnum, int tonum) : This method sets each bit from the specified fromnum (inclusive) to the specified tonum (exclusive) to the complement of its current value, i.e removes fromnum to tonum-1 values.
public void flip(int fromnum,int tonum) Parameters : fromnum : start number to begin flipping. tonum : last-1 number to end flipping. Return Value : This method does not return a value.
// Java code to demonstrate the// working of flip(int fromnum, int tonum) in Bitset import java.util.*; public class Flip2 { public static void main(String[] args) { // declaring bitset BitSet bset = new BitSet(6); // assigning values to bset bset.set(0); bset.set(1); bset.set(2); bset.set(3); // printing the original set System.out.println("The original bitset is : " + bset); // using flip(fromnum,tonum) to remove 1 and 2 bset.flip(1,3); // printing final bitset // 1 and 2 are removed System.out.println("The flipped bitset is : " + bset); }} |
Output:
The original bitset is : {0, 1, 2, 3}
The flipped bitset is : {0, 3}
