Can you tell me what I'm missing? Thank you!

2. Please design methods to solve the following problem. Please clearly list the method name, parameter list, and return type for each method. Get a String and a int number, N, from keyboard. Then, display the string at index 0, and then every Nth char of the string. So if N is 2 , use index 0,2,4,6, until the end of the string. Example 1: input: "Programming in Java", 10 output: Pg import java. lang.*; public class stringNum \{ public static void main(String[] args) \{ / getNthCharString(); public static String getNthCharString(String str, int n) {/ Scanner keyboard = new Scanner(System.in); System. out. println("Please enter a string."); String str = keyboard.nextLine(); System. out.println("Please enter a number."); int n = keyboard.nextInt(); for(int i=0; i}
