Mark writes a class Practice.java. This class needs to access the com.bar.Test class that is stored in the Test.jar file in the directory /practice. How would you compile your code? 

javac -classpath /practice/Test.jar Practice.java 

javac -classpath /practice/ Practice.java 

javac -classpath /practice/Test.jar/com/bar Practice.java 

javac -classpath /practice Practice.java
