I'm working with a linked list and getting this error message:
NoSuchElementException: No line found
public static void main(String[] args) {
Scanner Input = new Scanner(System.in);
String selection = null;
do {
System.out.println("\n\t\tMENU DISPLAY\n-----------------------------------------------");
System.out.println("a\tShow all records");
System.out.println("\nr\tRemove the current record");
System.out.println("\nf\tChange the first name in the current record");
System.out.println("\nl\tChange the last name in the current record");
System.out.println("\nn\tAdd a new record");
System.out.println("\nd\tAdd a deposit to the current record");
System.out.println("\nw\tMake a withdrawal from the current record");
System.out.println("\nq\tQuit");
System.out.println("\ns\tSelect a record from the record list to become the current record");
System.out.print("\nEnter a command from the list above, or q to quit: ");
selection = Input.nextLine();
switch(selection) {
case "a":
showAll();
break;

removeCurrent();

break;
case "t":

break;
default:
System.out.println("Error. Please only enter an option from the menu.\n");

Here is my stacktrace:

Exception in thread "main" java.util.NoSuchElementException: No line found

I tried doing some research on the exception, and upon changing while(true) to while(input.hasNextLine()), that only seems to make things worse. Although I don't get the error anymore, input.hasNextLine fails to show the menu more than once after an option has been entered. How can I solve this?
