8 Standard Java API
After reading lesson 8, you will be able to:
- Read the Java Standard API documentation
- Navigate the documentation to find various classes
- Understand when to use the Scanner class from the Java API
- Understand when to use Wrapper classes from the Java API
The Java API, Application Programming Interface, contains the set of classes and interfaces included with the Java Development Environment that are used to build application software. Each class is written in Java and runs on the JVM, Java Virtual Machine.
The idea of the API is to take commonly used classes and make them available to all developers, so they don’t need to recreate the code required for these common tasks.
This lesson introduces the topic of the Standard Java API and provides examples of some of the more commonly used classes included in the library.
