   Java isa programming language and environment invented by James Gosling and others in 1994.  Java was originally named Oak and was developed as a part of the Green project at the Sun Company.  Java is an object-oriented programming language with a built-in application programming interface (API) that can handle graphics and user interfaces and that can be used to create applications or applets.

   Package namescan be used to identify your classes.  Reusability of code is one of the most important requirements in the software industry.  Reusability saves time, effort and also ensures consistency.  In Java, the codes which can be reused by other programs is put into a “Package”.  A Package is a collection of classes, interfaces and/or other packages.  Packages are essentially a means of organizing classes together as groups.

   Java supportsa keyword called “package” for creating user- defined packages.  The package statement must be the first statement in a Java source file (except comments and white spaces) followed by one or more classes.

   Java offersthe real possibility that most programs can be written in a type-safe language.  However, for Java to be broadly useful, it needs to have more expressive power than it does at present.
