7 Getting Started with Java Programming A Simple Java Application A Simple Java Application Compiling Programs Compiling Programs Executing Applications Executing Applications A Simple Java Applet A Simple Java Applet Viewing Java Applets Viewing Java Applets Applications vs. Applets Applications vs. Applets

8 A Simple Application Example 1.1 //This application program prints Welcome //to Java! public class Welcome { public static void main (String[] args) public static void main (String[] args) { System.out.println("Welcome to Java!"); System.out.println("Welcome to Java!"); }} RunSource

9 Compiling Programs On command line On command line  javac file.java

10 Executing Applications On command line On command line  java classname

11 Example javac Welcome.java java Welcome output:...

12 A Simple Applet Example 1.2 /* This is an example of Java applets */ import java.awt.Graphics; public class WelcomeApplet extends java.applet.Applet { extends java.applet.Applet { public void paint (Graphics g) { public void paint (Graphics g) { g.drawString("Welcome to Java!",10,10); g.drawString("Welcome to Java!",10,10); }} Source

13 Creating an HTML File <body> <applet code="WelcomeApplet.class" width = 100 height = 40> width = 100 height = 40></applet></body></html>

14 Viewing Java Applets

15 Applet Viewer Utility appletviewer htmlfile.html Example: appletviewer WelcomeApplet.html Run Applet Viewer

16 Applications vs. Applets Similarities Similarities Differences Differences

17 Security Restrictions on Applets Applets are not allowed to read from, or write to, the file system of the computer viewing the applets. Applets are not allowed to read from, or write to, the file system of the computer viewing the applets. Applets are not allowed to run any programs on the browser’s computer. Applets are not allowed to run any programs on the browser’s computer. Applets are not allowed to establish connections between the user’s computer and another computer except with the server where the applets are stored. Applets are not allowed to establish connections between the user’s computer and another computer except with the server where the applets are stored.
