Consider the following Java statements.Scanner input = new Scanner(System.in);float radius = input.nextFloat();double area;Which of the variables in this piece of code are reference variables?Group of answer choicesinputradius, inputarearadius, area.

Select the correct answerWhat will be the output of the following Java code?  class Area {    public static void main(String args[])     {          double radii, pi, area;       radii = 6.6;       pi = 3.14;       area = pi * radii * radii;       System.out.println(area);    }   }Options136136.7784136.77136.7760000

Which of the following are valid assignment statement in Java? You can select more than one answer.Group of answer choicesfloat x = 3.5;int x = 3.5;boolean x = 0;double x = 3.5;int x = (int)3.5;

Which of the following methods is not present in the Scanner class in java?Options: Pick one correct answer from belownextLine();next();nextString();nextFloat();

Analyze the following code:  public class Test {   public static void main(String[] args) {     double radius;     final double PI = 3.15169;     double area = radius * radius * PI;     System.out.println("Area is " + area);   } } Group of answer choicesThe program has compile errors because the variable radius is not initialized.The program has a compile error because a constant PI is defined inside a method.The program has no compile errors but will get a runtime error because the radius is not initialized.The program compiles and runs fine.

Main MethodCreate a main method in the same class:This method will be the entry point for your program and allow user interaction.Inside the main method:Create a Scanner object to read user input.Prompt the user to enter the circle's radius using System.out.print.Use the Scanner object's nextDouble method to read the user-entered radius and store it in a variable.Create a Circle object.Call the setRadius method of the Circle object, passing the user-entered radius as an argument.Call the calculateArea method of the Circle object and store the returned area value in a variable.Print the calculated area to the console using System.out.printlnSubmit the following: Screenshot of source code and output, and Java source code file.
