Understand import statement and its importance.

Step 1 of 5
What is an import statement?

Import statement in java is used to import other existing packages
(all the classes in the package) or specific classes (a particular
class within the package) to the current class.
[Note: In real time, an import statement tells the compiler the
location of the java files that are been used in current class. In this
way compiler knows the location of the .java files and can convert
all of them into .class files which can be feed to JVM to be
converted into 0s and 1s.

Package A

If user wants to access Java files of package A, they can do
so by using import statements.- import A.*; - This statement
will help to import all the classes (in turn all the methods in the
classes) in package A.
