Compiling the Sample Programs

You can compile the samples by changing to the sample program's directory and compiling the *.java files, e.g.

cd Arcs_Curves
javac *.java

(This assumes javac is in your executible path, and you are using JSDK, v 1.2 or greater)

For your convenience, we have provided a script to compile all the samples -- execute compile.bat (for Windows) or compile.sh (for Solaris).

Running the Sample Programs

These sample programs are designed to run as standalone Java applications. To run them, you need to change to the sample program's directory and execute the java command on the class name, e.g.

cd Arcs_Curves
java Arcs

(This assumes java is in your executible path, and you are using JSDK, v 1.2 or greater)

For your convenience, we have provided another script to run the samples -- execute run.bat (for Windows) or run.sh (for Solaris).
