Normally you only get that error when executing a program.
Please copy the full text of the error message and paste it here.

Re: Exception in thread "main" java.lang.NullPointerException
Hi , at compile time it can not rise. whenever performing the any operations on null values it may be rise at run time.
Re: Exception in thread "main" java.lang.NullPointerException
Yes, you are right, the error occurs during run time. The output shows
"Exception in thread "main" java.lang.NullPointerException
at javax.swing.ImageIcon.<init>(ImageIcon.java:205)
at Login.<init>(Login.java:38)
at Login.main(Login.java:100)
Java Result: 1
BUILD SUCCESSFUL (total time: 1 second)"
Re: Exception in thread "main" java.lang.NullPointerException
There is a variable with a null value at line 38 where the code is trying to create an ImageIcon."Exception in thread "main" java.lang.NullPointerException
at javax.swing.ImageIcon.<init>(ImageIcon.java:205)
at Login.<init>(Login.java:38)
Check the code and make sure the variable does not have a null value there.
