How Do You Handle A Null Pointer Exception In Java?

The Java Programming Language suffers from null pointer exceptions when a piece of information it is looking for no longer exists in the system memory. This can typically happen at times when the system garbage collection has run or if the programmer has explicitly freed up resources that are still in use. Handling a null pointer exception involves running the program with an exception handling profile. Run the Java application with the -except parameter. You can accomplish this by typing Java -except. Enter “Yes” when asked if you would like to create a Pointer Exception Profile. Press the “Y” button at the prompt to ignore exceptions and log them to the hard drive. Pressing “N” will cause them to be ignored.
