Splitting user input and fill into a array with a loop (java)

Question

I need to make a calculator for students grades using java. The user types in the name and score for a student on a single line separated by commas. It needs to take 10 students details. But I can not work out how to split the user input string using commas, and fill it into my array. Any help would be appreciated. Thanks

public static void main (String[] args){

    Scanner scan = new Scanner(System.in);
    String[][] student = new String[10][];

    for (int index=1; index <=10; index++){
    String userinput = scan.nextLine();

You want String#split, which will return a String[].

Also, arrays in Java are zero-based, so you need

for(int index = 0; index < student.length; index++)

No need for the loop. If you want to fill in your array, you should use the split() method of the String class, like so:

String userInput = scan.nextLine();
// input comma-separated grades
String[] grades  = userInput.split(",");

And now you have a grades array with each element as an individual grade

The array is for the 10 students.
