Is the message you're getting a JVAB529: Public write authority on
"/directory"?  If so, it can be ignored for now.   

Look out for case-sensitivity on your Java command -- Java program name
searching can be case-sensitive, depending on the file system on the
AS/400. 

Confirm the exact name of the subdirectory containing the Sample.class
file (I'm presuming it's /Java/programs) and run this command before
trying the 'JAVA' command again: 
        ADDENVVAR CLASSPATH '/Java/programs' 

Now try: 
        JAVA Sample 

If you have the source in the same directory, you could start a qshell
session (presuming you have qshell installed) and recompile the java
source: 

        STRQSH                          # start the QShell 
        cd /Java/programs               # get to the right directory 
        javac Sample.java               # compile the Java source code 
         
Now you should be able to run: 
        java Sample
