Please help me fix this code Make it run out like the picture import java.util.ArrayList; import java.util.Random; import java.util.Scanner; public class FrogListApp { public static void main(String[] args) { final int MIN_WEIGHT = 1; final int MAX_WEIGHT = 25; // Step 3: Create an array list to store Frog objects ArrayList frogsList = new ArrayList<>(); // Step 4: Create a Scanner object Scanner scanner = new Scanner(System.in); // Step 5: Read an integer as the number of frogs // using prompt "Enter the number of frogs: " System.out.print("Enter the number of frogs: "); int numberOfFrogs = scanner.nextInt(); // Step 6: Read an integer as the random generator seed // using prompt // "Enter an integer as the random generator seed: " System.out.print("Enter an integer as the random generator seed: "); int seed = scanner.nextInt(); // Step 7: Create an Random object using the input seed Random random = new Random(seed); // Step 8: Use a for loop to create the specified number // of frogs and add them to the array list. // The weights of the frogs must be in the range // [MIN_WEIGHT, MAX_WEIGHT] and be generated by the // Random object created in Step 7 for(int index = 0; index < numberOfFrogs; index++) { int weight = random.nextInt(MAX_WEIGHT - MIN_WEIGHT) + MIN_WEIGHT; Frog frog = new Frog(weight); frogsList.add(frog); } System.out.println("All frogs before swapping:"); // Step 9: Use the enhanced for loop to print // out all frogs in the list, one per line for(Frog frog:frogsList) { System.out.println(frog.toString()); } // Step 10: Calculate the index of the last frog // in the list and store it in a variable int lastFrogIndex = frogsList.size()-1; // Step 11: Swap the first and last frogs in the list Frog temp = frogsList.get(0); frogsList.set(0, frogsList.get(lastFrogIndex)); frogsList.set(lastFrogIndex, temp); System.out.println("All frogs after swapping:"); // Step 12: Use the enhanced for loop to print // out all frogs in the list, one per line for(Frog frog:frogsList) { System.out.println(frog.toString()); } } }
