Java BitSet | intersects()
BitSet is a class defined in the java.util package. It creates an array of bits represented by 0s and 1s.
Syntax
public boolean intersects(BitSet set)
Parameter: The method accepts a mandatory parameter set, which is the BitSet to be checked for intersection.
Returns: The method returns a boolean indicating whether this BitSet intersects the specified BitSet.
Explanation: The method returns true if the specified BitSet has any bits set to true that are also set to true in this BitSet, otherwise false is returned.
Examples:
Input :
set1 : {1, 2, 4}
set2 : {}
Output :
false
Java
import java.util.*;
public class GFG {
public static void main(String[] args)
{
BitSet bs1 = new BitSet();
BitSet bs2 = new BitSet();
BitSet bs3 = new BitSet();
bs1.set( 0 );
bs1.set( 1 );
bs1.set( 2 );
bs1.set( 4 );
bs2.set( 4 );
bs2.set( 6 );
bs2.set( 5 );
bs2.set( 1 );
bs2.set( 2 );
bs2.set( 3 );
System.out.println( "bs1 : " + bs1);
System.out.println( "bs2 : " + bs2);
System.out.println( "bs3 : " + bs3);
System.out.println( "bs1 intersection bs3 = "
+ bs1.intersects(bs2));
System.out.println( "bs3 intersection bs1 = "
+ bs3.intersects(bs1));
}
}

Output:
bs1 : {0, 1, 2, 4}
bs2 : {1, 2, 3, 4, 5, 6}
bs3 : {}
bs1 intersection bs3 = true
bs3 intersection bs1 = false
