-Create a Listener, named MnemonicPrinter, that prints the mnemonics of the byte instructions that are executed by JPF.  Consider, for example,
+====== Lab 2 ======
-<html>
+Write a listener, named LongestPath, that keeps track of the length of a longest  path in the state space.  The method getDepth of the class Search might be helpful (see [[https://www.eecs.yorku.ca/course_archive/2019-20/W/4315/api/jpf/|JPF's API]]).  To make it a little easier, you do not have to consider state spaces with cycles.  A sample run can be found below.  It shows what type of output your listener should produce.
-<pre>
-public class HelloWorld
-{
-  public static void main(String[] args)
-  {
-    System.out.println("Hello World");
-  }
-}
-</pre>
-</html>
+To compile your listener, use
+<code>
+javac -cp /cs/fac/packages/jpf/jpf-core/build/jpf.jar:. LongestPath.java
+</code>
+or add /cs/fac/packages/jpf/jpf-core/build/jpf.jar as an external library to Eclipse.
+Also write an app, named Path, to test your listener.  Finally, write an application properties file to run JPF with your listener on the app.
+To receive feedback, submit your listener, your app, and your application properties file using the submit command **before** Tuesday January 28:\\
+<code>
+submit 4315 lab2 LongestPath.java Path.java Path.jpf
+</code>
