Assuming that a class with the main method exists and a reference variable andobject have been created using: Question qnew Question ();What is printed out from the following statement:int x = ((Object) q).points (5);System.out.println (x);a) Runtime ErrorOb) Compile Errorc) 515d) 151 In this section, please refer to the following classes to answer the questions.public class True False extends Question{public class Question{}public Question() {this (5);}public Question(int n) {}System.out.println("Q");}System.out.println("Q" + n);public int points (int n) {System.out.println(n);return n + 10;public double half(int n) {return points (n / 2);162 points)Saved}public TrueFalse() {}public TrueFalse(String s) {super(s.length());System.out.println(s);}System.out.println("TF");public int points (int n) {n += 20;}System.out.println(n);return n;

The programme creates an object of class Question. Using that object, the function points() is called.Inside the points() function, first the value of n is printed, which is 5, and then the n+10 value is returned from the function. This value is then printed inside the main() method.Therefore, the output will be: 5 15

Math class and its different methods

Java math class consists of arithmetic math methods that performs basic numeric operations such as finding the maximum or minimum of two values, rounding values, logarithmic functions, square root, and trigonometric functions, etc. The Math library functions can be accessed using the header Java.lang.Math. These math methods under Java math class are for our convenience.
