What is Java?
• Java is a high-level programming language developed by Sun Microsystems.
The Java Story
• Java was developed at Sun Microsystems, Inc. (Sun) by James Gosling.
• The language needed to be small, fast, reliable, and portable (hardware independent).
• With the goals it had achieved (smallness, speed, reliability, portability), Java was discovered to be ideal for web pages.
• Java can also be used to write stand-alone applications.
Java Technology
• A programming language
• A development environment
• An application environment
• A deployment environment
Features of Java
• Object-Oriented
• Portable and Platform-Independent
• Dynamically Linked
• Multithreaded
• Garbage Collected
Java Requirements
• Pentium 166 MHz or faster processor
• At least 48MB of RAM
o Using an applet within a Web Browser with JDK plug-in
• At least 64MB of RAM
o Graphics based application
Sample Java Program
Hello.java
public class Hello
{
public static void main (String[] args)
{
System.out.println(“Hello, World!”);
}
}
