– Group of similar types of classes, interfaces and subpackages.
1- Built in packages
– also called as predefined packages in java
i.e- java.lang, java.util, java.io etc

[To use class of other package, we have 3 options to choose]

Note– importing package doesn’t include subpackage
used to import only static member of a class instead of class.
