How can it be modified a little bit to print the board and have each tile labeled with a number to identify the space? I'm a beginner and would like to take this step by step in modifying the code. Thank you!

PROBLEM STATEMENT: Return the longest String! public class LongestString{public static String solution(String firstWord, String secondWord){// ↓↓↓↓ your code goes here ↓↓↓↓return null;}} Can you help me with this Java Question

public class Course{String name;String dept;int number;public Course (String n, String d, int n){name = n;dept = d;number = n;}public String toString(){return "Course " + name + " in " + dept + " #: " + number;}public static void main (String [] args){Scanner in = new Scanner(System.in);add 10 lines using the scanner and saving them as strings The input for each line will be entered a String, a space, another String, and an int. Parse the input string into those three items and make an instance of Course. Add the new Course instance to a generic ArrayList of Course. print out each Course in the ArrayList.
