Demo program in java

The IDE Demo is a mockup of an IDE (Integrated Development Environment) application that contains a complete, fully-featured help system.

To run the IDE demo, enter the following command at the command line:

java -jar JavaHelp_Home /demos/bin/idedemo.jar

After the demo starts, choose Help > Demo JDE — Help to activate the help viewer.

Object Demo

Lightweight Java components can be added to HTML topic pages using the tag. The JavaHelp system includes popup and secondary windows implemented using the JHSecondaryViewer component. The object demo shows how popup and secondary windows work.

To run the Object demo, enter the following command at the command line

java -jar JavaHelp_Home /demos/bin/object.jar

API Viewer

The JavaHelp release includes an API Viewer. This simple application is similar to the helpset viewer, except that the CLASSPATH includes a special ClassViewer navigator. The API Viewer presents javadoc -generated information derived from the JavaHelp source files.

The TOC in the API Viewer (the ClassViewer navigator) includes a top pane and a bottom pane. The top pane displays a list of the classes, interfaces, and exceptions that comprise the JavaHelp system. The bottom pane displays a hierarchy of components of a selected class, interface, or exception. Select a class in the top pane to view its constituent components in the bottom pane. Choose a component in the bottom pane to view it in the content viewer.

The data used by the ClassViewer Navigator is generated using a doclet (doclets are a feature of the Java TM 2 SDK). The API doclet is not included in this release of the JavaHelp system.

To run the API Viewer demo, enter the following command at the command line:

java -jar JavaHelp_Home /demos/bin/apiviewer.jar

Merge Demo

Demonstrates JavaHelp system helpset merging capabilities. For details, see the online help available from the Help menu in the merge demo program.

To run the Merge demo, enter the following command at the command line:

java -jar JavaHelp_Home /demos/bin/merge.jar

Newmerge Demo

Demonstrates JavaHelp system helpset merging capabilities. For details, see the online help available from the Help menu in the newmerge demo program.

To run the Newmerge demo, enter the following command at the command line:

java -jar JavaHelp_Home /demos/bin/newmerge.jar

Browser Demo

Demonstrates how the JavaHelp system can be used with applet-based applications running in web browsers. You can run demonstration by using either Netscape Navigator or Internet Explorer. The demo creates an applet button on an HTML page. When you click the button, the JavaHelp viewer displays the Holiday helpset. This demo requires some setup. You can find instructions for the demo in the file demos/browser/demo_instructions .

Search Example

The file demos/src/sunw/demo/searchdemo/ClientSearch.java shows how to extend the HelpSearch class to implement an alternate search engine.

Localized Helpsets

Localized demonstration helpsets (English, German, Japanese) for the IDE demo are included in the demos/hsjar folder. Be sure to choose the appropriate font in the JavaHelp viewer’s Set Fonts dialog box (choose Options > Set Font). You must have installed the appropriate Unicode fonts to be able to view the Japanese helpset.

Also, you use a different command to run helpsets. The command is:

java -jar hsviewer.jar [-helpset hs_name]

For example (on a Windows system):

C:\> java -jar c:\JavaHelp\demos\bin\hsviewer.jar 
-helpset c:\JavaHelp\demos\hs\newmerge\MergeHelp.hs

what is the error in this program class p3
public static void main(int age)
if(age>=18)
system.out.println(“eligible for election”);
>
else
system.out.println(“not eligible for election”);
>
>

Hey..there is a syntax error in your program! The “s” of “system” must be in caps…that is,
It should be —
System.out.println(“eligible…”); I hope it helps!!

Four mistakes: 1. main method should have String []args as arguments instead of age. Use public static void main(String args[])
2. age should be declared as a variable before using. Use int age=10;
3. System.out.println instead of system.out.println.
4.Closing bracket fro class p3 missing. Use > at last.

This page is awesome For beginners…it is very helpful…give me example programs which will be useful for real time projects

How can I take an array for example five separate words and place them on separate lines evenly using astericks to make up the number on both ends in relation to the number entered by the user? Is a program to do this possible?

console application that receives any size of matrix and one parameter which is the Manhattan distance, this is K. The result should be Yes/No. Yes if there are any two similar items (integers) in the matrix that are in a distance of K from each other or less. Input: 1. Number of rows. 2. Matrix rows one line after the other in a new line between each matrix line. 3. K value. Output YES/NO Here is a sample for an input and output:
