Most classes need to be imported before they can be used in an app. Why is every app allowed to use classes System and String without first importing them?
What will be an ideal response?
If every use of a class’s name in a program is fully qualified, there is no need to import the class. A class’s fully qualified name consists of the class’s package followed by the class name. For example, a program could use class Scanner without importing it if every use of Scanner in the program were specified as java.util.Scanner.
