Cannot acces (a class), bad class file, class file contains wrong class

Question

Hi,
I am trying to implement a Java package and I've never done this before. The package is called 'randomX' and I downloaded it from here: http://www.fourmilab.ch/hotbits/source/randomX/randomX.html
I downloaded the .tar file on my Windows Vista system, unzipped it, and dragged and dropped into(in my case): C:\Program Files\Java\jdk1.6.0_05\src\java\util
This is also the directory where Random.java is, so I figured it went there, plus the Java Documentation says that, I think.
The Java Docs are here: http://www.fourmilab.ch/hotbits/source/randomX/doc/
Thanks in advance,
Rommel.

No. That's not right - you need to put the JAR file into your classpath.

If it doesn't come with a JAR file then you'll need to build it first. Sounds like that might be outside your comfort zone.Thanks for the link and the tip. I have no idea what a JAR file is, much less how to build one.
However, the thing has a "Makefile" file. Can I build the JAR from this?
#   Makefile for randomX package
JAVA = /usr/java/jdk1.5.0_06
CLASSPATH = $(JAVA)/classes:..:.
SRC = randomX.java randomJava.java randomHotBits.java randomLCG.java \
      randomMCG.java randomLEcuyer.java randomXdemo.java
CLASS = $(SRC:.java=.class)
all:     
     javac -classpath ..  *java ; cp -p *class randomX
test:
     java randomXdemo
clean:
     rm -f *.bak *.class
     rm -rf doc
     mkdir doc
     rm -rf randomX
     mkdir randomX
RELEASE = $(SRC) Makefile
release:
     tar cfvz randomX.tar.gz $(RELEASE)
html:
     javadoc -classpath $(CLASSPATH) -d doc *.java
images:
     ( cd $(JAVA)/images ; tar cfv /tmp/ZZimages.tar . )
     rm -rf doc
     mkdir doc
     mkdir doc/images
     (cd doc/images ; tar xfv /tmp/ZZimages.tar )
     rm -f /tmp/ZZimages.tar
     touch randomX.java
.SUFFIXES:  .java .class
