copied!<p>Well this solution is not really good. but works.</p> <pre><code>public class FiveSecond { public static void main(String args[]){ new Thread(new Count(new Reader())).start(); } } class Count implements Runnable{ Reader r;Thread t; Robot ro; public Count(Reader t){this.r=t; try { ro=new Robot(); } catch (AWTException e) {e.printStackTrace();} } @Override public void run() { t=new Thread(r); //t.setDaemon(true); //[S2] t.start(); try{ Thread.sleep(5000); }catch(Exception e){} t.interrupt(); //Implicitly press the enter key in order to release the readLine() method :D //not recommended, and it's not a good idea, but works ro.keyPress(KeyEvent.VK_ENTER); ro.keyRelease(KeyEvent.VK_ENTER); /* * this is possible to save the strings lines in somewhere in order to access from invoker application * or send back the strings by socket, etc . . . */ System.out.println("number of entered lines "+r.getCount()+"\n"); //you would run this main as a process and get the number of counts //System.exit(r.getCount()); //[S2] } } class Reader implements Runnable{ private List<String> lines; private volatile int count; private BufferedReader br; public Reader(){ lines=new ArrayList<String>(); br=new BufferedReader(new InputStreamReader(System.in)); } @Override public void run() { try{String line; System.out.println("you have 5 second to detect a 2048 length character, then your system will broken"); while((line=br.readLine())!=null){ if(!Thread.currentThread().isInterrupted()){ count++;lines.add(line);}else{break;} } //for showing the lines entered //System.out.println(lines.toString()); }catch(Exception ex){} } public int getCount(){return this.count;} } </code></pre> <p>but the best approach is about running a separated process to count the lines, and you would just remove the <code>[S2]</code> comments to achieve it.</p>
