This is an existing service that will report back your own IP address. Once we have got our IP address in hand, we are going to use this IP address to call another service called ip. When performing this GET call to ip. Here we have two API calls where the second one depends on the first one. Throughout APIs, organizations can upgrade workflows to create them faster and even more effective.

Application : Since Java APIs can easily access the software components, the delivery of services, as well as data, is much more flexible. Efficiency : Once access is offered for a Java API, the content produced could be released instantly, and it is readily available for every single channel. This enables it to be distributed as well as sent out quickly. Integration : Java APIs enables content to be embedded by any site or perhaps software easier.

Runnable , ActionListener , Comparable are some of the examples of functional interfaces. Before Java 8, we had to create anonymous inner class objects or implement these interfaces. However, it is not mandatory to use this annotation.
