Class MonitorManager

java.lang.Object
  monitor.MonitorManager

public class MonitorManager
extends java.lang.Object

This class manages input output streams. Here, you can set(get) any defualt IO and error outputs. It is advised to use the setMonitorAsDefaultErrorOutput() method in the start of every program, to see clearly and save all Exceptions. For Example: //Start main.. public static void main(String [] args)throws Exception{ MonitorManager.setMonitorAsDefaultErrorOutput(); int x=5/0; }//end main.. ///////////Start Output://///// java.lang.ArithmeticException: / by zero at .main(.java:100) //////////End Output/////////// Another conveniant way if you are programming in non swing application. set the monitor to be the default IO and error output. This will empower your program to use interesting methods not applicable to the Dos screen like clear(). After the main method insert this before anything you code:

                        MonitorManager.setMonitorAsDefaultSystemIO();

 to capture input continue with you programming normally:
                        BufferredReader input=new BufferedReader(
                                                                        new InputStreamReader(System.in));
                        input.readLine();
                        

Test it you will like. The best thing about this is that you can insert this statement even in your old programs with out any extra effort to modify anything! Just one method call is enough to do the trick!
