Introduction

  • Over the years, many programmers learned structured programming. 

  • You’ll learn structured programming and object-oriented programming—the key programming methodology used by programmers today. 

  • Java has become the language of choice for implementing Internet-based applications and software for devices that communicate over a network.

  • There are now billions of Java-enabled mobile phones and handheld devices.

  • Java is the preferred language formeeting many organizations’ enterprisewide programming needs.


Java Editions

Java Standard Edition (Java SE) is a computing platform for development and deployment of portable code for desktop and server environments.

Java Enterprise Edition (Java EE) geared toward developing large scale, distributed networking applications and web-based applications. 

Java Micro Edition (Java ME)geared toward developing applications for small, memory-constrained devices, such as cell phones, pagers and PDAs.
