The first line of the input data file to the java application should consist of a single integer, n, between 1 and 6, equal to the number of lions in the simulation. (I provided a bit more capcity than you'll use, as your maximum number of lions is 6.) All subsequent lines are of the form:

Xg Yg Tg X1 Y1 T1 X2 Y2 T2 ... Xn Yn Tn

Where all the elements of each line are floating point numbers. Xg Yg Tg are the coordinates and heading of the gazelle, X1 Y1 T1 are the coordinates and heading of the 1st lion, etc.

Here is the jar file, Gazelle.jar, containing the classes of the Java application. You will need to have installed JDK1.1 (or higher) to run the application. Here are the instructions for installing jdk1.2.1 on a Windows machine.

Make sure the Gazelle.jar file is an element of the CLASSPATH variable.

  1. In Windows You should append ".\Gazelle.jar" to the end of your CLASSPATH shell variable. Then make sure "Gazelle.jar" is in your working directory when you run java. (Here is more on setting your CLASSPATH variable.) On my Windows machine, I installed JDK at C:\jdk1.2, so my CLASSPATH is C:\jdk1.2\src.jar;C:jdk1.2\lib\tools.jar;.\gazelle.jar
  2. In Unix I do the same thing, this time setting CLASSPATH via the commands: 

          CLASSPATH='/usr/local/java1.2/src.jar:/usr/local/java1.2/lib/tools.jar:.:./Gazelle.jar'
      export CLASSPATH
    You might want to place those lines in your ~/.profile file.
When all is set, run the application via the command: java Gazelle.
