Hi guys, trying to do an assignment here for class and I'm getting stuck on this null pointer exception (line 20 of the 1st block of code on here). I know what it means but every way I go about fixing it, it's just complaining even more in the compiler.






It is complaining about the "student[numStu].setName(stuName);" line and it's making my head about to explode to why it's happening. I'm really a beginner and it's the frustrations of java getting to me haha.

The best way to learn is to dry run your program.

It won't accept the line above it? "stuName = gradeFile.nextLine();"
Because basically what I'm trying to do is to set the "stuName" to the next line from the file.
 
It is sorta covered in the JavaRanch Style Guide.
