You mean you are doing fileIO homework

#

What's your problem then

#

Which exact part you wanna ask about

#

the readFilePopulateList method in CourseManager

#

it returns null if none of the if statements are met but its supposed to throw an exception i think

#

i tried to do that im just stuck

Ok let me see about that

#

ok

#

my code cant even really run because everything is null

#

after i enter a file name and type 1 to view course list it just does null exception cuz i need to add things

If file is empty,not need exception.Just show empty,and it's fine

#

If(file.isEmpty()){
throw new EmptyFileException();
}

#

If you still want excpetion,this is the code
