oop

I am new to java, I have seen in the code at many places where my seniors have declared as

List myList = new ArrayList(); (option1)

Instead of

ArrayList myList = new ArrayList(); (option2)

Can you please tell me why people use Option1, is there any advantages?

If we use option2, do we miss out any advantages or features?
