stream() is an instance method of BitSet which returns a stream of indices having the bit value set, i.e., true in the BitSet object. The indices returned are in order from lowest to the highest. The size of the stream is equal to the value returned by the cardinality() method.
The stream method is defined in the BitSet class. The BitSet class is defined in the java.util package. To import the BitSet class, check the following import statement.
import java.util.BitSet;
public IntStream stream()
The method has no parameters.
This method returns a stream of integers.
Let’s have a look at an example.
import java.util.BitSet;public class Main{public static void main(String[] args) {// Create empty BitSet objectBitSet bitSet = new BitSet();// Set the bit at index 2bitSet.set(2);// Set the bit at index 3bitSet.set(3);bitSet.set(6);// stream of indices at which bit is setbitSet.stream().forEach(index -> System.out.println("Set Bit found at index " + index));}}
