3. INTRODUCTION OF JAVA Java is a programming language and environment invented by James Gosling and others in 1994. Java was originaly 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.

4. KEY FEATURES OF JAVA Plateform Independence Encapsulation Dynamic binding Robust Distributed Portable Performance Multithreaded Interpreted & Compiler Architecture Neutral

5. FEATURES OF PACKAGES Package names can 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.

7. JAVA.LANG PACKAGE

8. JAVA.IO PACKAGE

9. CREATING A PACKAGE Java supports a 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.

10. ADVANTAGES OF JAVA 1.Java is easy to learn. 2.Java is object-oriented. 3.Java is platform-independent. 4.Java is distributed. 5.Java is secure. 6.Java is robust. 7.Java is multithreaded

11. DISADVANTAGES OF JAVA Slow Environment limitations Applet limitations imposed due to security model Uncertain status of security Programming language limitations Platform limitations General stability concerns

12. CONCLUSIONS   Java offers the 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.
