copied!<hr> <p><strong>Update</strong> : Thanks everyone! I've modified the program as per the suggestions and the code given below is the modified code.</p> <hr> <p><strong>Original Post :</strong> I've gone through some "Apply and Analyze" type of questions and in one question, the programmer has been asked to apply multithreading concept for three reservation counters of a cinema theater and calculate the total booking numbers and amount collected in a show.</p> <p>And I've written a program for the same which you can see below:</p> <pre><code>import java.io.*; import java.lang.*; class Cinema { int no=0,price=0; synchronized void reservation(int n,int p) { no=no+n; price=price+p; } } class Counter implements Runnable { BufferedReader br=new BufferedReader(new InputStreamReader(System.in)); Cinema c; int not,cost; Counter(Cinema c) { this.c=c; } public void run() { try { System.out.print("\nCounter 1"); System.out.print("\nEnter the no. of tickets :"); not=Integer.parseInt(br.readLine()); cost=not*150; c.reservation(not,cost); } catch(IOException e){System.out.print("\n"+e);} } } class CinemaMain { public static void main(String args[])throws IOException { Cinema c=new Cinema(); System.out.print("\nCounter 1"); Thread c1=new Thread(new Counter(c)); c1.start(); c1.join(); System.out.print("\nCounter 2"); Thread c2=new Thread(new Counter(c)); c2.start(); c2.join(); System.out.print("\nCounter 3"); Thread c3=new Thread(new Counter(c)); c3.start(); c3.join(); try { Thread.sleep(500); } catch(InterruptedException ie) { System.out.print("\n"+ie); } System.out.print("\nTotal no. of tickets :"+c.no); System.out.print("\nTotal Money collected:"+c.price); } } </code></pre> <p>I can compile it just fine, but when I run the program, this is what I get --><a href="http://puu.sh/5D2JN.png" rel="nofollow">LINK</a> (since I don't have 10 reputation, I couldn't post the image here, sorry!) I don't know why, it doesn't ask for input even though I've written the code to get input in the run method.</p>
