how to pass user input into multi-dimensional arrays

[ziongio]

I am trying to put my user input into a 7-dimension array. each dimension should be used to keep a certain trait of a student. When a user wants to see the info on the student, she/he inputs the student id and all the info is displayed. The info should not be saved to a file, just saved while the program runs.
I have been trying to solve this for a while. Thanks for the help. :)

I think you want a 2 dimensional array. I could be wrong though, please clarify.

Do you want an array where each slot is a 7 item array? Or something else?

int[][] a = new int[3][7];
where
int[0] = int[7]
int[1] = int[7]
int[2] = int[7]

It may honestly be easier to create a class which has all the student data and then work with a 1 dimensional array.

A 7 dimension array would be extremely challenging to keep track of.

it would be an array where each slot is a 6 d array, and each slot in the 6 d array would be a 5 d array, and so on, which would be pretty complex.

Even a 3d array would be quite complex and probably not what you want.

a 3d array of

int[][][] = new int[2][2][2];
would be
int[0] = int[][]
int[0][0] = int[]

I agree.

Using parallel arrays to model your data is a bad idea. Using multidimensional arrays are even worse. Do as suggested and use a class to hold your data instead.

So, would this be the case of someone focusing on coding a solution without thoroughly examining the problem?

A 7-dimensional array? That should be a clue.

I have a feeling he just misworded it. Im assuming he meant a 2 d array with 7 item arrays, like this:

String[][] people = new String[5];
people[0] = new String[7];
people[1] = new String[7];
...
people[4] = new String[7];

But again it would be better to use a class and a single array or arraylist.
