**Question 3:**The following code creates a 2D array of integers, and the nested for loops populate the array so that it is a multiplication table. In the last line of code, what should the array indices be in order to print out the correct answer (i.e., what replaces the question marks)?```javaint[][] my2DIntArray = new int[10][10];for (int i = 1; i <= 10; i++) { for (int j = 1; j <= 10; j++) { my2DIntArray[i-1][j-1] = i * j; System.out.print(my2DIntArray[i-1][j-1] + ", "); } System.out.println();}System.out.println("2 times 4 is " + my2DIntArray[?][?]);```What replaces the question marks?**Options:**A. 2 and 4 B. 3 and 5 C. 4 and 2 D. 1 and 3 E. 3 and 1 In the nested for loops, the actual value of the 2D array elements is calculated and stored using the formula `i * j`. Therefore, the correct indices to access `2 times 4` will be at `i = 2` and `j = 4`, but since arrays are zero-indexed, the actual indices to access `2 times 4` should be `(1, 3)`.Thus, the correct answer:**D. 1 and 3**

The required Java program has been solved in the next step.

3. The following code creates a 2D array of integers, and the nested for loops populate the array so that it is a multiplication table. In the last line of code, what should the array indices be in order to print out the correct answer (i.e., what replaces the question marks)? int my2DIntArray = new int [10] [10]; A. 2 and 4 for (int i = 1; i <= 10; i++) { for (int j = 1; j <= 10; j++) { my2DIntArray[i-1][j-1] = i*j; B. 3 and 5 System.out.print(my2DIntArray[i-1] [j-1] + ", "); C. 4 and 2 D. 1 and 3 System.out.println(); } E. 3 and 1 System.out.println("2 times 4 is " + my2DIntArray[?] [?]);

mergeAndRemove(int[], int[]) This is a public static function that takes a int[] and int[] for the parameters and returns an int[]. Given two arrays of integers. Your job is to combine them into a single array and remove any duplicates, finally return the merged array.
CODE IN JAVA design a program that grades arithmetic quizzes as follows: (Use the below startup code for Quizzes.java and provide code as indicated by the comments) 1. Ask the user how many questions are in the quiz. 2. Use a for loop to load the array. Ask the user to enter the key (that is, the correct answers). There should be one answer for each question in the quiz, and each answer should be an integer. They can be entered on a single line, e.g., 34, 7, 13, 100, 8 might be the key for a 5-question quiz. You will need to store the key in an array called "key". 3. Ask the user to enter the student's answers for the quiz to be graded. There needs to be one answer for each question. Note that each answer can simply be compared to the key as it is entered. If the answer is correct, add 1 to a correct answer counter. need this in a separate for loop from the loop used to load the array. 4. When the user has entered all of the answers to be graded, print the number correct…
