Keeping this in view, what is the purpose of an import statement in a Java program?
import is a keyword. import keyword is used to import built-in and user-defined packages into your java source file so that your class can refer to a class that is in another package by directly using its name. Use the '*' character to declare all the classes belonging to the package.
Beside above, does a Java program always have to include an import statement? There is no import statement needed anymore (which comes in handy if you need to use two classes with the same name within one Java file), but you put the entire path to the class, including package in the declaration/initialization of the variables. In this way, they can be about anywhere in the code.
Then, what is a Java package and how is it used?
