A developer is creating a class Book， that needs to access class Paper. The Paper class is deployed in a JAR named myLib.jar. Which three， taken independently， will allow the developer to use the Paper class while compiling the Book class？（）

A、The JAR file is located at $JAVA_HOME/jre/classes/myLib.jar

B、The JAR file is located at $JAVA_HOME/jre/lib/ext/myLib.jar

C、The JAR file is located at /foo/myLib.jar and a classpath environment variable is set that includes /foo/myLib.jar/Paper.class

D、The JAR file is located at /foo/myLib.jar and a classpath environment variable is set that includes /foo/myLib.jar

E、The JAR file is located at /foo/myLib.jar and the Book class is compiled using javac –cp /foo/myLib.jar/Paper Book.java

F、The JAR file is located at foo/myLib.jar and the Book class is compiled using javac –classpath /foo/myLib.jar Book.java
