pls explain step by step :)

Questions 1. Write a program that reads an integer from the user, then creates an array of integers of that length. It then fills the array with integers read from the user. 2. In your program's main class, define a static method printArray that takes an array of integers as its only argument and prints the elements of the array. You should print all the elements of the array on one line, separated by spaces, with no extra space after the last element. Extend your program from Question 1 to use this method to print the array after reading it. 3. Extend your program to print the index of the middle element of the array and the value stored in the array at that index (with an informative message). Explain in a comment how you decide what the middle is. 4. Extend your program to compute the minimum value in the array and print it out (with 5. Extend your program to read an integer from the user and add it to every element of 6. Extend your program to declare another integer array variable and make its value be an informative message) the array. Print the array after changing it (with an informative message) a copy of the first array. That is, its value should be a reference to a new array of the same length that contains the same element values (this is called a shallow copy) Print the first and last elements of the copy (with an informative message)
