Thread: How do I get my program to access and read a file, and put the contents into an array?

I am given a .txt file of columns of students. Each row contains last name, first name, major, credits completed, and gpa. I need to create a scanner to read from a file, create a printWriter to write to a file. I have the most useless textbook I bought for the class so I pretty much have to learn this on my own. Can someone help me finish this skeleton class?

Here is my txt file:
Bunker John Computer Science 42 3.14
Smith Jane Health Education 32 3.29
Wilson Robert Community Health 61 2.3
Clinton Alice Urban Studies 45 2.9
Podesta Stephanie Biology 92 2.8
Cronk Anthony Psychology 70 1.9
Smith Matthew History 33 1.2
Appletree Joshua Communication Sciences 40 3.4
Lucas Jill Criminal Justice 56 3.8
Sanders George Elementary Education 102 2.1
O'Brien William Nursing 99 3.2
Newman Lorraine Geography 40 3.1
Meszaros Mark International Business 56 3.9
Sedaris Sharon Environmental Sciences 78 3.5
Cormier Elizabeth Neuro Science 45 3.6
Peterson Nina Cognitive Science 73 4.0
Wilson Anna Chemistry 82 3.87

here is my main method:

can someone please just walk me through this? I'm a beginner so if you try to use crazy lingo on me or if you're just extremely broad I might as well just use my textbook.

Create a Scanner instance that reads the file: Scanner (Java Platform SE 7 )
When you have managed to read the file, start thinking about splitting up the lines: String (Java Platform SE 7 )
And so on. Do one step after the other.
