我还在学习http://programmingbydoing.com/a/name-age-and-salary.html

我收到此错误消息。谁能告诉我如何解决这个问题？如果我输入数字99.9，我会收到此错误。但如果我把99或99,9这不是错误。 i get this error

import java.util.Scanner;

public class NameAgeSalary    
{
    public static void main ( String[] args)
    {
        Scanner keyboard = new Scanner (System.in);
        String Name;
        int Age;
        double Salary;

    System.out.println( "Hello. What is your name?" );
    Name = keyboard.next();
    System.out.println();
    System.out.println( "Hi, " +Name+ "! How old are you?" );
    Age = keyboard.nextInt();
    System.out.println();
    System.out.println( "So you're " +Age+ ", eh? That's not old at all! ");
    System.out.println( "How Much do you make," +Name+ " ?" );
    Salary = keyboard.nextDouble();
    System.out.println();
    System.out.println( ""+Salary+ "! I hope that's per hour not per year! LOL!");
}
}

如果双重接受99和99,9，但99.9不接受，则将您的语言环境设置为逗号用作小数分隔符而不是点的值。

例如在美国，值1,234.56是正确的，而德国的相同数值则表示为1.234,56。

请检查语言和本地设置，并根据该设置输入值。
