Classes extending other classes - Sun Certified Java Programmer 310-065 Training Course - Part 4 | Java courses

In this video we will see how an class can extend other clas, but implement other interfaces.

Duration: 17:29 min

Summary: In this video, we continue our discussion of questions that cover "declaration and Access Control". We start with questions that talk about classes and interfaces. We looked at how classes extend other classes, but implement other interfaces. Then we talked about incorrect variable declarations. When declaring variables, we start the name of the variable with a letter, an underscore, or a dollar sign. We cannot start with a number or a pound sign. The other questions cover enums. Every enum comes with a static values() method that returns an array of the enum's values, in the order in which they are declared in the enum.
