java.util.NoSuchElementException: No line found

Question

I got an run time exception in my program while I am reading a file through a Scanner.

java.util.NoSuchElementException: No line found     
   at java.util         


        

Answer 1

I also encounter with that problem. In my case the problem was that i closed the scanner inside one of the funcs..

public class Main 
{
	public static void main(String[] args) 
	{
		Scanner menu = new Scanner(System.in);
        boolean exit = new Boolean(false);
    while(!exit){
		String choose = menu.nextLine();
        Part1 t=new Part1()
        t.start();
	    System.out.println("Noooooo Come back!!!"+choose);
		}
	menu.close();
	}
}

public class Part1 extends Thread 
{
public void run()
  { 
     Scanner s = new Scanner(System.in);
     String st = s.nextLine();
     System.out.print("bllaaaaaaa\n"+st);
     s.close();
	}
}

		 

The code above made the same exaption, the solution was to close the scanner only once at the main.
