A UNIX user named Bob wants to replace his chess program with a new one, but he is not sure where theold one is installed. Bob is currently able to run a Java chess program starting from his home directory /home/bob using the command:
	java -classpath /test:/home/bob/downloads/*.jar games.Chess
	Bob’s CLASSPATH is set (at login time) to:
	/usr/lib:/home/bob/classes:/opt/java/lib:/opt/java/lib/*.jar 
	What is a possible location for the Chess.class file?()
