Packages provide an alternative to creating procedures and functions as stand-alone schema objects, and they offer the following advantages:
Packages serve one major purpose: they make code cleaner.
By that, I mean that packages allow for easy associations of similar-purpose code to be placed together, and avoid problems with name-space collisions between similarly-named objects and methods in completely different contexts.
Packages are analogous to libraries in C - it's a convenient way to describe a set of related objects and methods, and make it simple to use those objects and methods in the proper context.
Java could survive without packages, but it would be much messier.
The supermost package of Java is the "java" package.
import package_name.*;where package_name is your package name.by using this syntax you can import an entire package.
A default package is a package with no name. You can create a Java class without putting package name on top of the code. This class is included in the "default package". Be careful not to be confused with java.lang, which is a package that contains Java's fundamental classes and get's imported by default.
The java.lang package is automatically imported for you.

Yes it is possible to draw in java by using AWT package. or by using javax package.

The Java 'this' installation package allows one to create installation programs for their Java based applications. One can download the program from Java.
Because, the java.lang package contains some of the most commonly used classes and utility functions of Java. As a result, almost all classes will be using some or all of those features. So, the creators of Java automatically imported this package in every class that you create to avoid the explicit import action for java developers

A user defined package is a package outside of the standard Java libraries.
You can import a package as many times as you want in Java. The compiler will just ignore any duplicates.
You use javac <filename> to compile a class or package.
