Complete Java SE 8 Developer Bootcamp - Static Imports

The video tutorial explains the use of constants and interfaces in Java, focusing on static imports. It covers how to define constants in interfaces, use static imports to access constants and methods without implementing the entire interface, and the use of wild cards in static imports. The tutorial also discusses the application of static imports with the Java Math class, highlighting the benefits and limitations of this feature.

What are constants typically defined as in a Java class?

• Public, static, and final

• Public, dynamic, and final

• Private, static, and final

• Protected, static, and final

Which of the following is NOT a constant defined in the 'safe driver' interface example?

• Average speed

• Maximum speed

• Safe following distance

• Minimum fuel level

What is the correct syntax for a static import in Java?

• import static

• static method import

• static import

• import static method

What is the main advantage of using static imports?

• They increase program execution speed

• They allow importing of private members

• They reduce the amount of code needed

• They automatically implement interfaces

What is a limitation of using wildcards in static imports?

• They can only import methods

• They require traditional imports for type inclusion

• They are recursive

• They are slower than regular imports

Why might you still need a regular import when using a wildcard in a static import?

• To include non-static members

• To specify the package name

• To import sub-packages

• To include the type name

How does a static import benefit the use of the Java Lang math class?

• It increases the execution speed of math operations

• It allows access to private methods

• It reduces the need to type the class name

• It automatically imports all classes in the package
