Q1. Produce a method that reads in a set of values (double) from the user and returns them. Use this header: public static double[] getNumsFromUser (String msgl, String msg2) The implementation of the method should start with a message to input the total number of array elements, followed by a message to enter all the array elements. The method returns the array of elements. The two strings msg1 and msg2 that are passed to the method as parameters will be the two messages that tell the user what to do. In the main class, use the following program outline to test this method: public class Q1 { public static void main(String[] args) { String s1 = "Enter number of students: "; String s2 = "Enter student grades: "; double[] numbers = System.out.println(Arrays.toString(numbers)); getNums FromUser(s1, s2); %3D public static double[] getNumsFromUser(String msg1, String msg2){ //your code goes here } Sample run Enter number of students: 4 Enter student grades: 12.5 23 11.5 27 [12.5, 23.0, 11.5, 27.0]

Question

Q1.
Produce a method that reads in a set of values (double) from the user and returns
them. Use this header:
public static double[] getNumsFromUser (String msg1, String msg2)
The implementation of the method should start with a message to input the total number of
array elements, followed by a message to enter all the array elements. The method returns
the array of elements. The two strings msg1 and msg2 that are passed to the method as
parameters will be the two messages that tell the user what to do.
In the main class, use the following program outline to test this method:
public class Q1 {
public static void main(String[] args) {
String s1 = "Enter number of students: ";
String s2 = "Enter student grades: ";
double[] numbers = getNumsFromUser(s1, s2);
System.out.println(Arrays.toString(numbers));
public static double[] getNumsFromUser(String msg1, String msg2){
//your code goes here
}
Sample run
Enter number of students: 4
Enter student grades: 12.5 23 11.5 27
[12.5, 23.0, 11.5, 27.0]

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…

The Lo Shu Magic Square is a grid with 3 rows and 3 columns shown below. The Lo Shu Magic Square has the following properties: The grid contains the numbers 1 – 9 exactly The sum of each row, each column and each diagonal all add up to the same number. This is shown below: Write a program that simulates a magic square using 3 one dimensional parallel arrays of integer type. Do not use two-dimensional array. Each one the arrays corresponds to a row of the magic square. The program asks the user to enter the values of the magic square row by row and informs the user if the grid is a magic square or not.
