What is the result of the following program?1: public class Squares {2:      public static long square(int x) {3:      long y = x * (long) x;4:      x = -1;5:      return y;6:      }7:      public static void main(String[] args) {8:      int value = 9;9:      long result = square(value);10:         System.out.println(value);11: } }*A. -1B. 9C. 81D. Compiler error on line 9.E. Compiler error on a different line.

What is the output of the given code?abstract class Shape{    int i = 111, j = 222;    abstract void calcArea();    abstract void calcVolume();} abstract class Quadrilateral extends Shape{    void calcArea()    {        System.out.println(i);     }}class Square extends Quadrilateral{    void calcVolume()    {        System.out.println(j);     }}public class Test{    public static void main(String[] args)    {        Square c = new Square();         c.calcArea();         c.calcVolume();              }}Select one:a.Compile time error because 'class Square' is not override all the abstract methods, so should declare it as 'abstract'b.Compile time error because trying to instantiate the 'class Square' which does not override all the abstract methodsc.Run time Errord.111222

Analyze the following code: public class Test { public static void main(String[] args) { int n = 2; square(n); } void square(int n) { System.out.print(n + " square is " + n * n); }}The program has a compile error because method square(int n) does not return a value.The program has a compile error because method square(int n) is not declared static.The program runs fine.The program prints2 square is 4
