BitSet clone() Method in Java with Examples

Last Updated : 27 Dec, 2018

The clone() Method Java.util.BitSet class is used to create a copy of an existing BitSet. The new BitSet is exactly equal to the existing one and is a mere copy of the previous BitSet. Syntax:

Bit_Set.clone()

Parameters: The method does not take any parameters. Return Value: The method just returns another copy of the existing BitSet. Below programs illustrate the working of BitSet clone() method in Java. Program 1:

Java

// Java code to illustrate clone()
import java.util.*;

public class BitSet_Demo {
    public static void main(String args[])
    {
        // Creating an empty BitSet
        BitSet init_bitset = new BitSet();

        // Use set() method to add elements into the Set
        init_bitset.set(10);
        init_bitset.set(20);
        init_bitset.set(30);
        init_bitset.set(40);
        init_bitset.set(50);

        // Displaying the BitSet
        System.out.println("Initial BitSet: " + init_bitset);

        // Creating a new cloned set
        BitSet cloned_set = new BitSet();

        // Cloning the set using clone() method
        cloned_set = (BitSet)init_bitset.clone();

        // Displaying the new Set after Cloning
        System.out.println("The new BitSet: " + cloned_set);
    }
}

Output:

Initial BitSet: {10, 20, 30, 40, 50}
The new BitSet: {10, 20, 30, 40, 50}

Program 2:

Java

// Java code to illustrate clone()
import java.util.*;

public class BitSet_Demo {
    public static void main(String args[])
    {
        // Creating an empty BitSet
        BitSet init_bitset = new BitSet();

        // Use set() method to add elements into the Set
        init_bitset.set(40);
        init_bitset.set(25);
        init_bitset.set(80);
        init_bitset.set(95);
        init_bitset.set(5);

        // Displaying the BitSet
        System.out.println("Initial BitSet: " + init_bitset);

        // Creating a new cloned set
        BitSet cloned_set = new BitSet();

        // Cloning the set using clone() method
        cloned_set = (BitSet)init_bitset.clone();

        // Displaying the new Set after Cloning
        System.out.println("The new BitSet: " + cloned_set);
    }
}

Output:

Initial BitSet: {5, 25, 40, 80, 95}
The new BitSet: {5, 25, 40, 80, 95}
