System.out.println("Sorry requested name not found.");
}
public static void howPopular(String chosenOne, PrintStream out, Scanner input)
{
if (input.hasNextLine())
{
String theName = input.nextLine();
Scanner linescan = new Scanner(theName);
String line = linescan.next();
line.toString();
int x = -1;
while (line.equalsIgnoreCase(chosenOne) && x <= 7)
{
int popular = linescan.nextInt();
x++;
int year = 2010+ (10 * x);
System.out.println(year + ": " + popular);
if (x <= 7)
{
out.println(year + ": " + popular + ", ");
}
