Another interesting thing is that when the second JBuilder instance starts its output is shown in the Messages Pane of the first JBuilder instance. By Alvin Alexander. Last updated: June 4, How to modify the JBuilder classpath by editing jbuilder. Scala 3 opaque types: How to create meaningful type names. Scala 3 modules: How to build modular systems. I prefer this method, which preserves the HTML formatting that is embedded in the JavaDoc data, to systems that convert the Java documentation into Microsoft "help" files.
Of course, writing code is easy. It's getting it to work that's hard. Perhaps the most important feature for any IDE is its debugger. Fortunately, the Borland JBuilder debugger does not disappoint. A screen shot of the debugger is shown below. When debugging, the browser window is reconfigured to support looking at your class's status. The tree structured file view is split into an upper window containing thread status and a lower window containing information about active variables.
Also, the left half of the browser gains some addtional tab controls at the bottom that control the operation of the debugger. Additionally, pop-up windows will display a variable's value in the source window in much the same way that Symantec's debugger works.
All of the standard debugging features are present: single step, watch points, break points, conditional break points, and so on. Of note is the thread support, which is outstanding.
In the thread window in the upper-left corner, you can click on the currently-executing line of any piece of code in any thread, and the source window will pop to that place in the code.
Furthermore, the lower-left window will display any local and global state that is visible to that thread. JBuilder's debugger definitely represents the new standard against which other Java debuggers will be measured. Along the left side of the source window, small dots indicate lines where breakpoints can be installed. Clicking on the dot highlights the line, and the breakpoint symbol appears. Another useful feature is "run to cursor" -- for those times when you don't want to single step through every iteration of a for loop.
Simply click on the line, select "run to cursor," and execution stops right there. A final area in which I found JBuilder to be particularly useful was its handling of the output from executing a Java application. The execution log is a window that contains all of the data sent to System.
However, when multiple projects are open, the execution log maintains separate tabs for each project! An example of this is shown below. As you can see in the image there are two tabs, one for "example" and one for "BASIC," the current project. This separation is essential when building multiple class libraries at the same time because it keeps you from mixing up the output from the two projects.
Sometimes it is the little things. I really like that one can print Java source code to a color printer and have it come out with its fonts and syntax highlighting intact. If I could customize the page headers and footers and specify a "two-up" output two pages of source code printed side by side on a landscape output page , it would be perfect. The support for Java 1. While JDK 1. As I stated earlier, the debugger is very nice as well: It gives a large amount of information in an easy-to-comprehend way.
Much of the debugging is "point-and-shoot" style, which some users like I do and some don't believing that "gdb" stands for God's DeBugger. I believe it's sufficient to find even the most difficult thread deadlock bugs. First, you can't set the default background and foreground colors in the display.
Instead, you first have to set them for your entire desktop and then JBuilder will notice the changes. File messages show the number of leaves and the warning and error count. The message types are differentiated with icons and by color: Errors are red with an error icon, warnings are shown in blue and display a warning sign, informational messages are black and carry a file icon and debugging messages are black and prepended by a bug icon.
Clicking on a file name will open that file, clicking on a message that contains location information will open the file containing the message and move the caret to the nominated location. Although Jalopy ships with sensible default settings mimicking the Sun Java coding convention , you most likely want to configure the formatter to match your needs adding copyright headers, tune Javadoc handling and the like.
For such, Jalopy comes with a graphical configuration tool that lets you interactively customize the settings. See Chapter 2, Configuration for an in-depth discussion of the available options.
