Java Result: 1

my program turn normally
suddenly, in the last execution it shows this error:
Exception in thread "main" java.lang.NullPointerException
at ca.uvic.csr.shrimp.Shrimp.main(Shrimp.java:65)
Java Result: 1


i didn't change any thing in this class

A reference/pointer was null at line #65 in the main method of class ca.uvic.csr.shrimp.Shrimp; without seeing any code this is all that can be concluded ...

kind regards,

Jos

Too bad... but how should be determine what went wrong without even seeing your code?

thanks but i find the error
it is a problem of diplay
