Java Editor and IDE

Both JPad Pro and SitePad Pro support the Java IDE. Java features include support for Sun's Java tools, ANT, java build and rebuild commands, visual debugger, code folding (outlining), smart keys, smart indent, code completion, syntax coloring, Jad (a Java decompiler) and source code browser.

Editing Java with JPad Pro

Use the Java commands to easily build, debug and run Java programs. F1 keyword help is available for JavaDocs. Just place the caret in a Java keyword, class or variable and hit F1 to get help. The Java IDE will work with any JDK version including version 5 and it is easy to switch between JDK versions.

If you are new to Java and to programming, we recommend Java in Easy Steps .

Smart Complete

The Java IDE includes smart complete (often called auto complete). Smart complete can use any JDK version and your own libraries. If source code is not available then smart complete will get its information from class files. To use smart complete type a ctrl + space or a '.' + <tab>. You can also just pause after typing a '.' (if you turn that option on by going to View/Smart Keys...).

Project Support

Creating a Java project that includes existing files is easy. For example, to create a project that will build a debug version for all java.* classes do the following:

1. Extract the source files from the src.zip archive in your JDK folder to the src folder in the same location.
2. Create a new project using the File/New Project... command. Call it java.
3. Add a build package by using the Project/Add Build Package command.
   1. In the Add Build Package dialog select the Java type.
   2. Set the source path to point to the java source folder.
   3. Leave all other options set to their default values.
   4. Click OK. You have now added over 1000 source files in multiple directories to the project.
4. If you are using JDK 1.4 you will need to add the -source 1.4 option to the command line in JDK/Edit Options... to avoid compile errors.
5. Set the build mode in the JDK menu to Debug Build.
6. Choose Build from the JDK menu.

Building the java project will result in debug versions of all the classes in java and its subfolders. Now when you debug and step into a java.* class debug information will be available including local variables.

Browsing Source Code

To inspect the source code you can use the class panel located in the workspace panel. The class panel includes each class and its methods and fields. Double clicking on an item in the class view will open the corresponding source code for that item. You can also open the source code for any errors generated from the compiler or from the runtime by just double clicking on the error.

Specialized Tools

In addition there are a number of specialized Java tools. The Java IDE includes support for Jad (a Java decompiler) and ANT.
