The JDK file is key to developing APIs in Java and consists of:Ī Java compiler is a predefined program that converts the high-level, user-written code language to low-level, computer-understandable, byte-code language during the compile time.

Next, let's look at a few of the things we can do with interfaces. If you notice that many classes belong to a parent class with the same method actions but different behavior, then it's a good idea to use an interface. In this case, the implementation methods for ArrayList, LinkedList, and Vector are all different, which is a great scenario for using an interface.
