help needed

/* * Major Method Project * * You are taking over a project from a co-worker who has been fired for lying about being able to code Java. * You must now pick up from where he left off, luckily he was decent at commenting his code, just had a terrible attitude. * * Sample Run: * Here are the numbers in the array: * 21 41 25 89 36 80 57 64 91 75 * Here are the numbers in the array reversed: * 75 91 64 57 80 36 89 25 41 21 * Please give me an integer value and an insert point between 0 - 9 * 2 * 3 * * Here are the numbers in the array final result: * 75 91 64 2 57 80 36 89 25 41 */ import java.util.Scanner; import java.util.ArrayList; //append your last name to the class name, and saveAs the file as the same thing class MethodProj { //insert the integer in the index position and move all elements right (the 9th index will fall off) public static void insertValue(int array[], int num, int index) { } //reverse the order of the elements public static void reverse(int rev[]){ } //print the array public static void printit(int x[], String s){ } //randomize() method will fill in elements with random numbers from 10 - 99 public static void randomize(int x[]){ } /*you do not need to do anything to this main method, you need to make the methods above that they call work.*/ public static void main(String[] args) { Scanner scan = new Scanner(System.in); int [] randomNums = new int [10]; //populate with random numbers by calling the method randomize(randomNums); //display the random numbers by calling the method printit(randomNums, ""); //reverse the array element order reverse(randomNums); //display the random numbers by calling the method printit(randomNums, " reversed"); //ask for two integers; inserted number and insert index System.out.println("\nPlease give me an integer value and an insert point between 0 - 9"); int num = scan.nextInt(); int index = scan.nextInt(); //insert the value in the index point by calling the method insertValue(randomNums, num, index); //display the final result printit(randomNums, " final result"); } }
