Initializing ArrayList in one line in Java: best ways
Hello everyone! I'm a beginner Java developer, and I have a problem with initializing an ArrayList.
I know that you can add elements one by one using the `add()` method:
```java
ArrayList list = new ArrayList<>();
list.add("Apple");
list.add("Banana");
list.add("Orange");
```
But this takes 4 lines of code! It seems not very convenient, especially when you need to create a small list with fixed values, for example, for test data or configuration.
I've seen that in other languages (like Python or JavaScript) you can do this:
```python
# Python
my_list = ["Apple", "Banana", "Orange"]
```
And in Java I tried this syntax, but it doesn't work:
```java
ArrayList list = new ArrayList<>(){"Apple", "Banana", "Orange"};
```
