Notice that a package should lowercase and that you name it Student,
so as in the exercise, name it studentpackage.
Rule of thumb, if you put in a directory named foo, a java file named
bar.java, and that the directory foo will serve as a package, you
should have a line in bar.java at the top:
package foo;
Then compile exactly as it is done in the exercise.
It should work.
Except that you will probably have to remove the old class files
beforehand.
That is (adapt to your system), assuming you are in the myjavaprograms
directory:
cd anotherpackage;
rm -f *.class
cd ..
cd studentpackage;
rm -f *.class
cd ..
javac studentpackage/*.java
java -classpath . studentpackage.StudentRecordExample
(rm -f maybe del on your system, the reminder should be the same)
In StudentRecordExample, you have a line:
package Student;
change it to package studentpackage;
