How to compile and run java files from sub-directory

I'm trying to compile .java files and store them in a sub-directory called bin. I then want to run the generated .class files from the main directory. How can I do this?

Here's my Makefile:

# java compiler
JCC = javac

# output directory
OUTDIR = bin/

# compilation flags
JFLAGS = -g -d $(OUTDIR)

# default target entry
default: A.class B.class C.class

A.class: A.java
    $(JCC) $(JFLAGS) A.java

B.class: B.java
    $(JCC) $(JFLAGS) B.java

C.class: C.java
    $(JCC) $(JFLAGS) C.java

# To start over from scratch, type 'make clean'.
# Removes all .class files, so that the next make rebuilds them
clean:
    $(RM) $(OUTDIR)*.class

What I want to do:

  1. make
  2. java bin/A

You must specify the bin directory as the classpath of the JVM, using the -cp option

java -cp bin A

A being the fully qualified name of the class to run.
