Java BitSet clear() method

The clear() method of Java BitSet class is used to set the bits in the BitSet to false. There are various overloaded clear() methods available in BitSet class.

1. Java BitSet clear() method

The clear() method set all the bits in the BitSet to false.

2. Java BitSet clear(int bitIndex) method

The clear(int bitIndex) method set the bit of specified index to false.

3. Java BitSet clear(int fromIndex, int toIndex) method

The clear(int fromIndex, int toIndex) method set the bits to false from specified inclusive fromIndex to exclusive toIndex.

Syntax:

public void clear()
public void clear(int bitIndex)
public void clear(int fromIndex, int toIndex)

Parameter:

DataType	Parameter	Description
int	bitIndex	It is the index of bit value
int	fromIndex	It is the index of bit from which the false value of bit starts.
int	toIndex	It is the index of bit at which the false value of bit ends.

Returns:

Exception:

Method	Exception
clear()	NA
clear(int bitIndex)	IndexOutOfBoundsException - if the specified index is negative
clear(int fromIndex, int toIndex)	IndexOutOfBoundsException - if any of the specified fromIndex or toIndex is negative or fromIndex is larger than the toIndex.

Compatibility Version:

Method	Compatibility Version
clear()	Java 1.4 and above
clear(int bitIndex)	Java 1.0 and above
clear(int fromIndex, int toIndex)	Java 1.4 and above

Example of Java BitSet clear() method

Example 1

import java.util.BitSet;
public class BitSetClearExample1 {
	public static void main(String[] args) {
	      // create a bitset
	      BitSet bitset = new BitSet();

	      // assign values to bitset
	      bitset.set(0);
	      bitset.set(1);
	      bitset.set(2);
	      bitset.set(3);
	      bitset.set(4);


	      // print the sets
	      System.out.println("bitset: " + bitset);
	      bitset.clear();
	      // print bitset after clear
	      System.out.println("result bitset: " + bitset);
	}
}

Output:

bitset: {0, 1, 2, 3, 4}
result bitset: {}

Example of Java BitSet clear(int bitIndex) method

Example 2

import java.util.BitSet;

public class BitSetClearExample2 {
	public static void main(String[] args) {
	      // create a bitset
	      BitSet bitset = new BitSet();

	      // assign values to bitset
	      bitset.set(5);
	      bitset.set(10);
	      bitset.set(15);
	      bitset.set(20);
	      bitset.set(25);


	      // print the sets
	      System.out.println("bitset: " + bitset);
	      bitset.clear(10);
	      // print bitset after clear at index 10
	      System.out.println("result bitset: " + bitset);
	}
}

Output:

bitset: {5, 10, 15, 20, 25}
result bitset: {5, 15, 20, 25}

Example 3

Example of Java BitSet clear(int fromIndex, int toIndex) method

import java.util.BitSet;

public class BitSetClearExample3 {
	public static void main(String[] args) {
	      // create a bitset
	      BitSet bitset = new BitSet();

	      // assign values to bitset
	      bitset.set(5);
	      bitset.set(10);
	      bitset.set(15);
	      bitset.set(20);
	      bitset.set(25);


	      // print the sets
	      System.out.println("bitset: " + bitset);
	      bitset.clear(10,25);
	      // print bitset after clear from index 10 to 25
	      System.out.println("result bitset: " + bitset);
	}
}

Output:

bitset: {5, 10, 15, 20, 25}
result bitset: {5, 25}
