java remove first element from list

in java, you can remove the first element from a list using various classes that implement the `list` interface, such as `arraylist` and `linkedlist`. below is a tutorial explaining how to do this, including code examples.

### removing the first element from a list in java

#### step 1: import required packages

#### step 2: create a list

you can use either `arraylist` or `linkedlist`. here are examples of both:

#### step 3: remove the first element

to remove the first element from the list, you can use the `remove(int index)` method, where you specify the index of the element you want to remove. the index of the first element is `0`.

here's how you can remove the first element from both an `arraylist` and a `linkedlist`:

#### step 4: display the remaining elements

#### complete example code

here’s the complete code that combines all the steps:

### output

when you run the above code, you will see the following output:

### conclusion

removing the first element from a list in java is straightforward using the `remove(int index)` method. this method works for both `arraylist` and `linkedlist`. just remember to check if the list is not empty before attempting to remove an element to avoid `indexoutofboundsexception`.
