I am running Ubuntu 11.10. Running Java 7.0.1 with NetBeans. I wrote a java
program with a loop that reads a 26000 character text file (NVRAM.TXT) into
a character array. It worked fine. I ran the program numerous times over
four days. I have not made any changes to the java file. The program is
listed below. It has only 24 lines. Today when I run it, it has weird
errors referenced toline numbers 2442, 2685 and 1620. When I click on those
error messages it shows lines in
a huge completely different program - a program that I never wrote. I cut
and pasted the source (24 lines) of the offending file into a new empty java
file in a new project. The new project and file have different names than
the original names. It runs fine with the new name - no errors. The file
name that has the problem is Nvj5.java. That is the file selected and
displayed when I click RUN FILE. It is the file listed below. Even though it
is selected and displayed when I click RUN FILE my system is running some
other huge file (with errors) instead. The errors is copied below. Has
anyone ever heard of a problem like this? Please help. I asked questions in
a Java news group but they haven'tcome up with anything yet.
TIA Bill S.
