The issue I’m having is that the for loop with the comment never executes for any input I provide. This is a method that depends on no output being passed to or back from it from a main menu.
There is a method being called that initilizes dogList with values.
public static void main(String[] args) {
Scanner scan = new Scanner(System.in); //scanner object
addMonkeySpecies(); //add species to monkey species list for later validation
//while loop that persists until users enter Q regardless of case
while (!command.equalsIgnoreCase("q")) {
//display menu options
displayMenu();
command = scan.nextLine(); //get user command
//if-else tree for user selections
//terminate program selection
if (command.equalsIgnoreCase("Q")) {
System.out.println("nExiting program . . . Goodbye!");
break; //breaks loop, terminates program
}
//intake a new dog selection
else if (command.equalsIgnoreCase("1")) {
intakeNewDog(scan);
}
//intake a new monkey selection
else if (command.equals("2")) {
intakeNewMonkey(scan);
}
//reserve a animal selection
else if (command.equals("3") ) {
reserveAnimal(scan);
}
//print all available dogs
else if (command.equals("4")) {
printAnimals("dog");
}
//print all available monkeys
else if (command.equals("5")) {
printAnimals("monkey");
}
//print all non reserved animals in service option
else if (command.equals("6")) {
printAnimals("available");
}
//all other invalid input
else {
System.out.println("nPlease enter a valid selection.");
}
}
}
public static void initilizeDogList() {
Dog dog1 = new Dog("Spot", "German Shepherd", "male", "1", "25.6", "05-12-2019", "United States", "in service", false, "United States");
Dog dog2 = new Dog("Rex", "Great Dane", "male", "3", "35.2", "02-03-2020", "United States", "Phase I", false, "United States");
Dog dog3 = new Dog("Bella", "Chihuahua", "female", "4", "25.6", "12-12-2019", "Canada", "in service", true, "Canada");
dogList.add(dog1);
dogList.add(dog2);
dogList.add(dog3);
}
public static void reserveAnimal(Scanner scan) {
System.out.println("Enter animal type to reserve [Dog / Monkey]:");
String animalType = scan.nextLine();
if (animalType.equalsIgnoreCase("dog")) {
System.out.println("Enter dog's name to change reserve status: ");
String dogName = scan.nextLine();
System.out.println("if dog");
for (Dog dog : dogList) { //this is the loop that never executes
System.out.println("for loop");
if (dog.getName().equalsIgnoreCase(dogName)) {
System.out.println(dog.getName() + " is currently reserved: " + dog.getReserved());
System.out.println("Enter new reserved status [Yes / No]: ");
String reserveInput = scan.nextLine();
boolean reserved;
while (!reserveInput.equalsIgnoreCase("yes") && !reserveInput.equalsIgnoreCase("no")) {
if (reserveInput.equalsIgnoreCase("yes")) {
reserved = true;
} else if (reserveInput.equalsIgnoreCase("no")) {
reserved = false;
} else {
System.out.println("Enter a valid reserve status - only [Yes / No] accepted.");
}
}
}
}
}
RESULTS:
Rescue Animal System Menu
[1] Intake a new dog
[2] Intake a new monkey
[3] Reserve an animal
[4] Print a list of all dogs
[5] Print a list of all monkeys
[6] Print a list of all animals that are not reserved
[q] Quit application
Enter a menu selection:
3
Enter animal type to reserve [Dog / Monkey]:
dog
Enter dog's name to change reserve status:
bella
if dog
//here it returns to the main menu as if it never kicks the for loop in action it doesnt even display the print line entered for testing

@JustAnotherDeveloper called it. method to initialize lists was never called resulting in the for loop not having anything to iterate over in the array list.
