Executable Launcher (top)

An executable file launcher can execute an external executable file repeatedly at certain intervals. if we generate a jar file with source code, it is: Launcher.jar. You can run it with the following DOS command:Java-jar Lib\launcher.jar Getprocessstate.bat5000 indicates that the Getprocessstate.bat file is executed every 5000 milliseconds. source contains 2 files Worker.java and Launcher.java

Worker.java file:

Package Com.teleca.robin;import Java.io.BufferedReader;import java.io.IOException;import Java.io.InputStreamReader; import Javax.swing.JLabel;import Javax.swing.JTextField; Public class Worker extends Thread {private Boolean loop=true;private Boolean paused=false;private int cnt=0;final Private JLabel consoletext;Worker (JLabel lable)    {consoletext=lable;    }private long interval=1000;void SetInterval (long interval)    {This.interval=interval;    }private String executablefilename;void Setexecutablefilename (String file)    {if (executablefilename!=null&&file!=null)     {if (!executablefilename.equals (file))cnt=0;     }Executablefilename=file;    }Public void Dopause ()    {paused=true;    }Public void Doresume ()    {Paused=false;interrupt ();    }Public void Die ()    {Loop=false;    }Public Void Run ()    {While (loop)     {if (paused| | Executablefilename==null)     {try {Thread.Sleep (+);} catch (Interruptedexception e) {//TODO auto-generated catch block//e.printstacktrace ();}     }Else     {BufferedReader stdout = null;try {Process p = null;String line = null;p = runtime.getruntime (). EXEC (executablefilename, NULL, NULL);stdout = new BufferedReader (new InputStreamReader (P. getInputStream ()));While (line = Stdout.readline ()) = null) {System.out.println (line);    }stdout.close ();Stdout=null;} catch (IOException e) {e.printstacktrace ();}finally{if (stdout!=null)try {stdout.close ();} catch (IOException e) {//TODO auto-generated catch blocke.printstacktrace ();}   }cnt++;if (consoletext!=null)Consoletext.settext ("Execute the file" +cnt+ "Times");try {Thread.Sleep (interval);} catch (Interruptedexception e) {//TODO auto-generated catch block//e.printstacktrace ();}     }     }System.out.println ("exit!");    }}
