Java collections 'remove' method

[dvas0004]

Java Collections all have the remove method. The remove method actually takes two types of arguments:

1. An object. Java will remove a matching object from the collection
2. A primitive int. Java will remove the object in the collection at the index position specified by the int

For example:

List<String> demo = new ArrayList<>();
demo.add('demo1');
demo.add('demo2');

//example of (1)
demo.remove('demo2');

//example of (2)
demo.remove(0)
