parameter in threads

[Mario Gimenez]

Hi.
I don't know how put a parameter for something like this:

Pseudo-code:

    
public static void main
     
   for (x=0; x< 50; x++){
    
       Thread myThread = new Thread(x);
       myThread.start();

   }      


run

MyClass mc = new MyClass();
mc.sendMessage(x);

this its possible??

Anybody knows another way to do this???

Thanks in advance...

What you do want? Do you want to pass an integer to a method? Yes that is possible :P

class MyThread extends Thread {

    int px;

    MyThread(int x) {
        px = x;
    }

    public void run() {
        System.out.println("Send message - " + px);
    }
}

public class Test {

    public static void main(String[] args) {
        for (int x = 0; x < 50; x++) {
            Thread myThread = new MyThread(x);
            myThread.start();
        }
    }
}

Here is the project how send one message.

   

>>MyClass

 public static void main(String args[]) {
	   
	   setMQEnvironment();
	   mensaje = loadMessage();
	   
	   try{
		   sendMessage(mensaje,qManager);
		   
	   }catch (MQException ex){
            System.out.println("An MQ error occurred : Completion code " + ex.completionCode +" Reason code " + ex.reasonCode);
       }catch (java.io.IOException e){
            System.out.println("An error occurred while writing to the message buffer: " + e );
       }
  
   } 
   
   public static void setMQEnvironment(){
       MQEnvironment.hostname = "***.***..****..***";
       MQEnvironment.port = ****;
       MQEnvironment.channel = "SYSTEM.DEF.SVRCONN";
       MQEnvironment.CCSID = 850;
       
       
   }
 
   public static void sendMessage(String aMessage, String qManager)throws MQException, IOException{
	     
     	 
         qMgr = new MQQueueManager(qManager);
         
         int openOptions = MQC.MQOO_OUTPUT ; 
         
         
         MQQueue system_default_local_queue = qMgr.accessQueue(queue ,openOptions);
         MQMessage message = new MQMessage();
         
         message.messageId = MQC.MQMI_NONE;
         message.characterSet = 819;
         message.format = MQC.MQFMT_STRING;
         message.correlationId = MQC.MQCI_NONE; 
         
         //message.persistence = MQC.MQPER_PERSISTENT;
         message.writeString(aMessage);
         
         System.out.println("Envio el mensaje");
         MQPutMessageOptions pmo = new MQPutMessageOptions();
         system_default_local_queue.put(message,pmo);
         system_default_local_queue.close();
         qMgr.disconnect();
         System.out.println("Se desconecto");
         
   }
   
   
   public static String loadMessage(){
	   
	   File archivo = null;
	   FileReader fr = null;
	   BufferedReader br = null;
	   
	   	   
	   //Try to read the file
	    archivo = new File("D:\\Mensajes MQ\\Mensajes OK Nuestros\\ACNI001 - DESE.txt");
	    
		
	try{
		
		fr = new FileReader (archivo);
        br = new BufferedReader(fr);
		
		String linea;
		while ((linea = br.readLine()) != null){
			qLoadedMessage +=linea;
			System.out.print(linea);
			
		}
		
		}catch(Exception e){
	        e.printStackTrace();
	        System.out.print("No se pudo leer el archivo...");
	     }finally{
	        // En el finally cerramos el fichero, para asegurarnos
	        // que se cierra tanto si todo va bien como si salta 
	        // una excepcion.
	        try{                    
	           if( null != fr ){   
	              fr.close();     
	           }                  
	        }catch (Exception e2){ 
	           e2.printStackTrace();
	        }
	      }
	
   
	return qLoadedMessage;
   }

 

Now I want to use this to send many messages (whit threads or another ways....),
Because I need change a part of the message in each call I need pass a string parameter via Thread.
Because I need to know if its possible pass a String parameter to a thread.

for example...

>>Main..
for (x= 0; x< 50; x++){
Thread t = new Thread(x);
t.start();

}

>>run
MyClass mc = new MYclass();

mc.sendMessage(x); ----> this method it will replace the main method in the code I wrote before.



I hope I describe my doubt.




Thanks a lot.
