Packages are containers-for-classes used to keep the class namespace compartmentalized.
Using Package,
1. We can define classes inside a package that are notaccessible by the code outside that package.
2. We can define class members that are only accessible by code inside that package.
3. We can have a class stored in a package withoutconcern that it will collide with some other class (havin same name), stored else where.
Package is basically a collection of predefined or ready-made classes that can be used in your java program to make shorter as well as easier. Package- import java.lang.*; is always implicitly called when you write a java program.
The supermost package of Java is the "java" package.
The java.lang package in Java is automatically imported for you.
The java.lang package is automatically imported for you.
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.
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.
Yes it is possible to draw in java by using AWT package. or by using javax package.
Because, we dont have the package which we want perform the specific task in the lib. Thatz why we need to create packages own and importing it.
You use javac <filename> to compile a class or package.
