Installing JBuilder

• Jbuilder 3.5 is provided on your CD
• Open the MyComputer icon, and use right-click to
  explore
• Double click JB35?windows
• unzip the 4 files into some temporary folder
  (e.g. c\temp). This requires PKUnzip or similar
• For each in turn (foundation, docs, samples and
  opentools), find the install.exe file and double
  click. This installs everything into
  C\JBuilder35 by default
• The executable is in C\JBuilder\bin\JBuilder.exe
  (or use your start menu to launch)

3
Running JB for the first time

• When running JB for the first time, you will be
  asked for a serial number and a key
• shhhhhh...........
• Serial number xa32-?5n6h-5398g
• Access key zd4-?7a

4
Using JBuilder

• A group of files are collected together into a
  project.
• Each project has its own .jpr file
• For each project, make a folder and put the Java
  files you need in there, e.g.
• C\fred\java\MyFirstProject
• ...Instrument.java
• ...MyInput.java
• ...Saxophone.java
• ...InstrumentTest.java etc

5
Making a new project

• Choose File?New Project
• Follow the wizard.
• Replace ....\untitled\untitled.jpr with, e.g.
  ...\MyProject\MyProject.jpr
• Do not mess with the rest of the path here
• You have the option of preparing some
  documentation for your project here (optional)

6
Adding files to your project

• Use the 'AddFile' icon () to add all the java
  files you will work with
• Under Project?Project Properties?Paths, add the
  Folder containing your code to the Source Path
• Under Project?Project Properties?Run, choose the
  file containing your main method
• Build or make your project
• Run your project

7
Avoiding problems

• Keep all files and only files associated with one
  project in a single folder
• Make sure that folder is listed as one of the
  sources in the project properties list
• Make sure you have chosen which file contains the
  main method

8
Why bother?

• With practice, managing multiple files becomes
  much easier
• Documentation is immediately available (right
  click on any identifier to browse its
  documentation)
• Building graphical interfaces is greatly
  simplified
• Finding out what classes are available is greatly
  simplified
• Syntax highlighting! Helps debugging.
• A debugging tool is also included
