Given the fоllоwing Jаvа cоde: import jаva.util.HashSet;import java.util.Set;class DataPoint {    int id;    String label;    double value;    DataPoint(int id, String label, double value) {        this.id = id;        this.label = label;        this.value = value;    }    @Override    public boolean equals(Object obj) {        if (this == obj) return true;        if (obj == null || getClass() != obj.getClass()) return false;        DataPoint other = (DataPoint) obj;        return Double.compare(other.value, this.value) == 0;    }    @Override    public int hashCode() {        return label != null ? label.hashCode() : 0;    }}public class HashSetTest {    public static void main(String[] args) {        Set dataSet = new HashSet();        dataSet.add(new DataPoint(101, "A", 3.14));        dataSet.add(new DataPoint(102, "B", 2.71));        dataSet.add(new DataPoint(103, "A", 3.14));        dataSet.add(new DataPoint(104, "B", 3.14));        dataSet.add(new DataPoint(105, "B", 2.71));        System.out.println("Set size: " + dataSet.size());    }} What would be the printed size of the HashSet?
