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 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); } } |
Initial BitSet: {10, 20, 30, 40, 50} The new BitSet: {10, 20, 30, 40, 50}
Program 2:
// 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); } } |
Initial BitSet: {5, 25, 40, 80, 95} The new BitSet: {5, 25, 40, 80, 95}
