Problem with nextDouble when reading txt files

Question

Hello, im very new to java and im trying to read a double number from a text file but I get an error if i dont write int values, for example:
my txt file:
John Smith
32.5part of my Java code:
out.println(myScanner.nextLine());
out.println(myScanner.nextDouble());(myScanner read my text file)
but I get this error:
Exception in thread "main" java.util.InputMismatchException
at java.util.Scanner.throwFor(Scanner.java:840)
at java.util.Scanner.next(Scanner.java:1461)
at java.util.Scanner.nextDouble(Scanner.java:2387)
at TeamFrame.<init>(TeamFrame.java:15)
at Baseball.main(Baseball.java:14)
Im following the Java for dummies book and according to the book this should work.

Answer 1

(Please post using the {code} tags - you put {code} at the start of your code and again at the end so that it's readable when it appears here. If nobody has replied to your post you can edit it and put the tags in now.)
The code you posted doesn't correspond to the data you posted originally.
Also when you say "nextLine()" the scanner reads and return s a line and it moves to the next line. But when you say "nextInt()" or "nextDouble()" it doesn't move to the next line even when there's nothing but an int or a double on the line it's reading. That's because there is a newline character and the scanner stops just before that.
The solution is to say nextLine() straight after every nextInt() or nextDouble(). The nextLine() - whose result you just throw away - will move you to the next line.
You do this in the case of the int you read, but not in the case of the doubles.

    int nrPlayers = myScanner.nextInt();

    for (int num = 1; num <= nrPlayers; num++) {
        String name = myScanner.nextLine();
        double average = myScanner.nextDouble();
