JAVA PROGRAM - File saving and loading

1. Using the code below implement an option to save the plants to a file. You must also be able to load the saved information from a previously saved file.

2. Use the file class and/or scanner class for file saving/loading methods

3. You MUST submit a sample file that can be loaded into your program without any changes (except the file path)

import java.util.ArrayList; import java.util.Scanner;

public class FlowerPack { public static void main(String[] args) { try{ ArrayList flowerPack= new ArrayList <>(); Scanner input=new Scanner(System.in); int choice; String name, color, ID; boolean poisonous,edible,medicinal,smell,thorns; while(true) { System.out.println(" 1.
