534470.3640684.qx3zqy7StartThis challenge activity consists of a series of auto-generated, randomized questions allowing unlimited submissions. You mustcorrectly answer a question at each level before proceeding to the next level. The purpose of this first level is to familiarizeyourself with how the autograder works.1. Click the "Start" button to begin the challenge activity.2. Copy the code provided and paste the code into the code window. The following code uses scnr.nextInt () to read in avalue for variable numCarrots. Then, uses System.out.println () to output the value of numCarrots, followed by "carrots" and a newline.numCarrots = scnr.nextInt ();System.out.println (numCarrots + " carrots");3. Click the "Check" button to test your code. Our autograder automatically runs your program several times, testing differentinput values each time to ensure your program works for any values. An explanation is also provided.Note: You can only edit lines where the line number (shown on the left) are white. Lines with grey line numbers cannot be edited.Learn how our autograder works1 import java.util.Scanner;23 public class Carrots {4567891011}public static void main(String[] args) {Scanner scnr = new Scanner(System.in);int numCarrots; // Creates an integer variable named numCarrots* Your code goes here */}

8) Now use the Rectangle class to complete the following tasks: - Create another object of the Rectangle class named box2 with a width of 100 and height of 50. Note that we are not specifying the x and y position for this Rectangle object. Hint: look at the different constructors) Display the properties of box2 (same as step 7 above). - Call the proper method to move box1 to a new location with x of 20, and y of 20. Call the proper method to change box2's dimension to have a width of 50 and a height of 30. Display the properties of box1 and box2. - Call the proper method to find the smallest intersection of box1 and box2 and store it in reference variable box3. - Calculate and display the area of box3. Hint: call proper methods to get the values of width and height of box3 before calculating the area. Display the properties of box3. 9) Sample output of the program is as follow: Output - 1213 Module2 (run) x run: box1: java.awt. Rectangle [x=10, y=10,width=40,height=30] box2: java.awt.…
Integer userValue is read from input. Assume userValue is greater than 1000 and less than 99999. Assign tensDigit with userValue's tens place value.
