Example:
In the example below, the java.util.BitSet.size() method is used to find out the number of bits currently used in the given BitSet.
import java.util.*;
public class MyClass {
public static void main(String[] args) {
//creating a BitSet
BitSet BSet = new BitSet();
//populating BitSet
BSet.set(10);
BSet.set(20);
BSet.set(30);
BSet.set(40);
BSet.set(50);
System.out.println("Size of BSet: " + BSet.size());
//adding one more element in the BitSet
BSet.set(100);
System.out.println("Now, Size of BSet: " + BSet.size());
}
}
The output of the above code will be:
Size of BSet: 64 Now, Size of BSet: 128
