Preliminaries:
- "Click on" means move the mouse cursor over the item and press and release the left mouse button.
- Similarly "Right click on" means move the cursor over the item and press and release the right mouse button. The right mouse button usually brings up a menu of properties for the selected item.
- "Click and hold" means hold the left mouse button down while you drag the mouse. For example "Click and hold on A->B" means move the mouse to A, hold down the left mouse button while dragging the mouse to B, then release.
- Do not double click (two quick left mouse presses) unless explicitly indicated.
To access items through a menu (e.g. the File menu appearing on the top bar of the workspace), left click on the menu item. A pull-down menu will appear. Move the cursor over the action you want (e.g. New Project ) and left click. In the handout we will describe this sequence as "Select the New Project option on the File menu".
Starting JBuilder:
System.out.println("Hello world, my name is YOURNAME");
so that the program is:
package simpleproject;
public class HelloWorld {
public static void main(String[] args) {
System.out.println("Hello world, my name is YOURNAME");
}
}
Click on the Run using the defaults to run the program. You should see a "Hello world" message in the bottom window.
When you re-enter JBuilder, you can get a previous application through
the Reopen icon on the Menu Bar. Alternatively you
can open a project through the File menu.
Adding a user-defined package to your project:
- From the Project menu select Project Properties
- Select the Required Libraries tab
- Click Add
- Click New
- Give the library a name. For example, suppose you wanted to add the cs1.jar file that you stored in C:\java\cs1.jar. Give the library a descriptive name such as CS1Library. Then click add and find the actual file or directories that you want to add.
- Exit out of all the windows by clicking OK four times
- From the Project menu select Default Project Properties
- Select the Required Libraries tab
- Click Add
- Under the UserHome directory click cs1 (the one from step 1)
- Click OK (twice).
