[SOLVED] Line number: ?

[Azndaddy]

Hi, just having a problem at the moment with my code. its only part of the code from the class

PHP Code:

    public void execute()
    {
        buffer = new Buffer();
        System.out.print("Line number: ");
        int pos = Integer.parseInt(getInput());
        buffer = editor.getCurrentBuffer();
        System.out.println(pos +": " +buffer.getLines().get(pos-1));
        buffer.setPos(pos-1);
        editor.setCurrentBuffer(buffer);
    } 


What im trying to do is, when i type in the command goto, it will print the line number in which i chose. example when i type goto, then press 3, it will print out line numbeer 3. but the problem im having is, when i type in goto, 0 which is the line number, it gives me an error.

how could i fix this so that when i type goto, 0 line, it print out the following
Line number: ?

Thanks

nvm

Fixed it

added the following line

PHP Code:

if(getCurrentBuffer().getPos() == 0)

else

System.out.println("Line Number: ?");
