to pass arguments to the objects constructor. If there is no arguments then they are left blank. Let's say your object has a constructor with parameters String, Int, and Double. When you create the object, you put Object lobster = new Object("String", 8, 12.3); They are placeholders for potential arguments

() is used to pass values to that objects constructor. If no values are being passed, the () are left empty.

because class_name() is a constructor which is a method also . you can pass a prameter or not depending on the constructor which you can define it in its class or if you didnt the java will do that automatically
