Expert Solution & Answer
Chapter 24, Problem 20RE
Explanation of Solution
Matching the given error messages:
Consider the below command:
java -classpath derby.jar;. TestDB
When executing the above command, the possible error messages are matched with its corresponding error conditions as follows:
Usage: java [-options] class [args...]
The above error message can occur when the “derby.jar” and “.” does not contain a colon “:” when running the command on the operating systems such as Linus, UNIX, or Mac OSX.
- Suppose if we run Linux, UNIX, or Mac OSX, then it should have been separated by a colon (:) but not a semicolon as a path separator, so that the above error can be avoided.
Therefore, the given error message is matches with the error condition “derby.jar and . should have been separated by a colon on this
Exception in thread “main” java.sql.SQLException: No suitable driver found for jdbc:derby:BigJavaDB;create=true
The above error message can occur when there is no suitable driver found for the connection.
- When we run a java database program, the “bin” folder should contain all the required “JAR” files, so that, the above error can be avoided.
Therefore, the given error message matches with the error condition “The derby.jar file was not present in the current directory.”
Exception in thread “main” java.lang. NoClassDefFoundError: TestDB
The above error message can occur when there is no class definition found for the program.
- When we run a Java database program the required class files should be present in the JDK bin directory so that the above error can be avoided.
Therefore, the given error message matches with the error condition “The TestDB.class file was not present in the current directory”
Exception in thread “main” java...

Java Graphics
(Bonus
In this lab, we'll be practicing what we learned about GUIs, and Mouse events. You will need to
implement the following:
A GUI with a drawing panel. We can click in this panel, and you will capture those clicks as a
Point (see java.awt.Point) in a PointCollection class (you need to build this).
The points need to be represented by circles.
Below the drawing panel, you will need 5 buttons:
O
о
о
○
An input button to register your mouse to the drawing panel.
A show button to paint the points in your collection on the drawing panel.
A button to shift all the points to the left by 50 pixels.
The x position of the points is not allowed to go below zero.
Another button to shift all the points to the right 50 pixels.
"
The x position of the points cannot go further than the
You can implement this GUI in any way you choose. I suggest using the BorderLayout for a panel
containing the buttons, and a GridLayout to hold the drawing panel and button panels.
Regardless of how…
