I cant take full names in my array

Question

public static void main(String[] args) 
{
    Scanner input = new Scanner(System.in);
    String[]repName = new String[5];
    double[]salesAmount = new double[5];
    System.out.println("Please Enter Sales Reps Name Followed By Monthly Sales: \n");
    for (int i = 0  ; i < repName.length; i++ ) 
    {
        System.out.print("Sales Rep (Full Name):  "  );
        repName[i] = input.nextLine();

        System.out.print("Monthly Sales:  € "  );

        salesAmount[i] = input.nextDouble();
        System.out.println();
    }

The code will only allow me to input a full name once, ie John Doe. It will not let me enter it with other doubles in the array. Why is this?

Are you entering the double value in the same line as Full Name? — Anil, Feb 10 '15 at 15:17

I got your error. When you enter double, you press enter. That is a new line which was taken instead of another name. Then it is expecting double but you are entering another name. So you get an input Mismatch.

After input.nextDouble() write input.nextLine();

The code should look like this.

 public static void main(String[] args)
{
    Scanner input = new Scanner(System.in);
    String[]repName = new String[5];
    double[]salesAmount = new double[5];
    System.out.println("Please Enter Sales Reps Name Followed By Monthly Sales: \n");
    for (int i = 0  ; i < repName.length; i++ )
    {
        System.out.print("Sales Rep (Full Name):  "  );
        repName[i] = input.nextLine();

        System.out.print("Monthly Sales:  € "  );

        salesAmount[i] = input.nextDouble();
        input.nextLine();
        System.out.println();
    }
}

Thank You that worked perfect – Ian Murray Feb 10 '15 at 15:31 — Ian Murray, Feb 10 '15 at 15:31

I have run your code, It's running well I think while entering salary you have not hit Enter key of your keybord.

I found that you are using loop over the length of person name. I think it is something wrong.

An easy way to solve this is to just use the next method instead of nextLine.

repName[i] = input.next();
