Question

I am using a scanner to populate an array with data. It seems to work because when I print (player[i].Name) in the “if” statement it prints a value. But when I try to print this value outside of the statement (players[1].Name), it gives a null value.

int i = 0;
        while (scanner.hasNextLine()) {
                if (scanner.hasNext()) {
                players[i].Name = scanner.next();
                System.out.println(players[i].Name);
                }
                if (scanner.hasNext()) {
                players[i].Position = scanner.next();
                System.out.println(players[i].Position);
                }
                if (scanner.hasNext()) {
                players[i].Height = scanner.next();
                System.out.println(players[i].Height);
                }
                 if (scanner.hasNext()) {
                players[i].Weight = scanner.next();
                System.out.println(players[i].Weight);
                }
               i++;      
            }//end while

You’re doing this 10x (for each i):

 // Get all possible scanner entries for all possible lines for i=0
 while (scanner.hasNextLine()) {
        if (scanner.hasNext()) {
            players[i].Name = scanner.next();
 // .. then repeat getting all scanner entries for all lines for i=1...

Maybe this is what you meant:

int i = 0;
while (scanner.hasNextLine()) {
    if (scanner.hasNext()) {
        players[i].Name = scanner.next();
        System.out.println(players[i].Name);
        i++;
    }
}

Or maybe even this:

int i = 0;
while (scanner.hasNextLine()) {
    while (scanner.hasNext()) {
        players[i].Name = scanner.next();
        System.out.println(players[i].Name);
        i++;
    }
}

Or this:

int i = 0;
while ((i < 10) && scanner.hasNextLine()) {
    while ((i < 10) && scanner.hasNext()) {
        players[i].Name = scanner.next();
        System.out.println(players[i].Name);
        i++;
    }
}
