The idea is to make sure that classes are easy to locate. Also, the directory college is accessible through CLASSPATH variable, i.e., path of parent directory of college is present in CLASSPATH.

For example if a package name is, then there are three directories, college, staff and cse such that cse is present in staff and staff is present college. Package names and directory structure are closely related. We can reuse existing classes from the packages as many time as we need it in our program. A package is a container of a group of related classes where some of the classes are accessible are exposed and others are kept for internal purpose. After that, we can simply write an import class from existing packages and use it in our program.

Packages can be considered as data encapsulation (or data-hiding).Īll we need to do is put related classes into packages.

A default member (without any access specifier) is accessible by classes in the same package only. A protected member is accessible by classes in the same package and its subclasses.

Providing controlled access: protected and default have package level access control.

Making searching/locating and usage of classes, interfaces, enumerations and annotations easier.

For example there can be two classes with name Employee in two packages, and .Employee

Package in Java is a mechanism to encapsulate a group of classes, sub packages and interfaces. ISRO CS Syllabus for Scientist/Engineer Exam.ISRO CS Original Papers and Official Keys.GATE CS Original Papers and Official Keys.
