File reading & Writing

[coarse fable]

I've got my code to read and write to text files, but when I try to save to the file, it just makes a blank one. Not sure what's causing this. Any help would be appreciated, as I'm sure I've overlooked something really simple. I know my code is messy and not nice, but I tried to work with as many new things as I could on this project and I've already learned a ton, so the next one will be better. I also know there are many improvements to be made, but I want to keep my original base so I can see how I improve from project to project.

here is full code: https://pastebin.run/gn-h-5njjdh7

and here are the snippets that are used to read/write.

    static void ReadFromFile(ArrayList<String> contactList) {
        try {
            FileReader readFileContact = new FileReader("ContactList.txt");
            BufferedReader readContact = new BufferedReader(readFileContact);

            String tempContact;

            while ((tempContact = readContact.readLine()) != null) {
                contactList.add(tempContact);
            }

        }catch (IOException e) {
            e.printStackTrace();
        }

    }```
```java
    static void WriteToFile(ArrayList<String> contactList) {
        try {
            FileWriter writeFileContact = new FileWriter("ContactList.txt");
            BufferedWriter writeContact = new BufferedWriter(writeFileContact);

            for (String contact : contactList) {
                writeContact.write(contact);
            }

        } catch (IOException e) {
            e.printStackTrace();
        }
    }```

cant paste the rest but I use `WriteToFile` at the end of add,edit,delete and exit. Meaning it first runs my normal code to perform the action and then I added `WriteToFile();`.

Like this.
```java
                    case 1:
                        addContact(contactList, scanner);
                        WriteToFile(contactList);
                        break;```

Figured it out. I was using try instead of try-with-resource when writing meaning it never closed for anybody ever having the same issue.

Old Code

    static void WriteToFile(ArrayList<String> contactList) {
        try {
            FileWriter writeFileContact = new FileWriter("ContactList.txt");
            BufferedWriter writeContact = new BufferedWriter(writeFileContact);

            for (String contact : contactList) {
                writeContact.write(contact);
            }

        } catch (IOException e) {
            e.printStackTrace();
        }
    }```

Fixed Code
```java
    static void WriteToFile(ArrayList<String> contactList) {
        try (FileWriter writeFileContact = new FileWriter("ContactList.txt");
            BufferedWriter writeContact = new BufferedWriter(writeFileContact)) {

            for (String contact : contactList) {
                writeContact.write(contact);
            }

        } catch (IOException e) {
            e.printStackTrace();
        }
    }```
