Scanners and class

I am a little confused! We are doing classes, constructors and methods in class at the moment and I get the basics. Leap forward to 2am in the morning and 4 hours of searching on the net for a solution to my question and I am back at stackoverflow looking for advice.

I have built my class and in it I have my get and sets. I will add my class now.

 public class staff 
     {
        private String empName;
        private int prefix;
        private int dialCode;
        private int telNum;
        private double grossSalary;


    public staff( String name, int prefix1, int dial, int celNum, double salary)
     {
        empName = name;
        prefix = prefix1;
        dialCode = dial;
        telNum = celNum;
        grossSalary = salary;
    }

The next part is where I am getting confused. I am now trying to populate this all using a Scanner but I am getting an error. As always I am not looking for an out right answer but more a nudge in the right direction. Here is the second part to my code.

    import java.util.Scanner;

public class staffInfo 
{
    public static void main(String[] args) 
    {
        Scanner input = new Scanner(System.in);

        String staffName  [] = new String [4];
        int staffPrefix   [] = new int    [4];
        int staffDialCode [] = new int    [4];
        int staffCellNum  [] = new int    [4];
        double staffSalary[] = new double [4];

        int i = 0, j = 0;

        for(j = 0; j < staffName.length; j++)
        {
            for(i = 0; i < staffName.length; i++)
            {
                System.out.print("Please enter staff name and press return : ");
                staffName [i] = input.nextLine();
                System.out.print("Please enter there cell number prefix : ");
                staffPrefix [i] = input.nextInt();
                System.out.print("Please enter dialing code : ");
                staffDialCode[i] = input.nextInt();
                System.out.print("Please enter cell number : ");
                staffCellNum[i] = input.nextInt();
                System.out.print("Please enter there salary : ");
                staffSalary[i] = input.nextDouble();
            }
            staff staff[j] = new staff(staffName,staffPrefix,staffDialCode,staffCellNum,staffSalary);
        }

    }

}

Thanks in advance for any help you may offer me.
