Consider the Java code given below. import java.util.*; import java.util.stream.*; class Player { private String name; int point; //Constructor to initialize instance variables public String toString() { return name; } } public class Test { public static void main(String[] args) { var pArr = new ArrayList<Player>(); pArr.add(new Player("Sharan", 150)); pArr.add(new Player("Virat", 500)); pArr.add(new Player("Rahul", 100)); pArr.add(new Player("Sanju", 250)); Map<Boolean, List<Player>> playMap; playMap = pArr.stream() .collect(Collectors.partitioningBy(p -> p.point >= 250)); System.out.println(playMap.get(false)); } } Choose the correct option. Consider the code given below. class Doctor implements Cloneable{ private String name; private String[] qualification ; public Doctor(String n, String[] q) { name = n; qualification = q; } //method setName(String name) to initialize name //method setQualification(int indx,String q) to initialize //qualification at a particular index //method getName() to return name //method getQualification(int indx) to return qualification //at a particular index public Object clone() throws CloneNotSupportedException{ return super.clone(); } } public class Testclone { public static void main(String[] args) throws CloneNotSupportedException{ String[] q = {"MBBS", "MD", "M.Ch"}; Doctor d1 = new Doctor("Mathew", q); Doctor d2 = (Doctor)d1.clone(); Doctor d3 = d1; d2.setQualification(1, "MS"); d3.setName("John"); System.out.println(d1.getName() + " " + d1.getQualification(1)); System.out.println(d2.getName() + " " + d2.getQualification(1)); System.out.println(d3.getName() + " " + d3.getQualification(1)); } } Choose the correct option. Method `Stream.iterate(e, f)` returns an infinite sequential ordered Stream produced by iterative application of a function f to an initial element e, producing a Stream consisting of e, f(e), f(f(e)), ...\ Based on the above information, consider the code given below, and answer the question that follows. import java.util.stream.*; public class Test { public static void main(String[] args) { Stream.iterate(10, n -> n - 1) .map(n -> n * 3) .filter(n -> n % 5 == 0) .limit(4) .forEach(x -> System.out.print(x + " ")); } } What will the output be?
