I am wondering if there is any simple way for creating a console that

a stuff like that,just a
standard way.

java.lang.System.setOut() and java.lang.System.setErr() will allow you
to change standard output and standard error streams to something else,
like the afore mentioned JTextArea. (Not automagically, you'll have to
write some code to get it all to work properly.)

And if the original poster want an example then I had something
on the shelf.

import java.io.ByteArrayOutputStream;
import java.io.PrintStream;

public class CaptureOutput {
     public static void main(String[] args) {
         try {
             PrintStream save = System.out;
             ByteArrayOutputStream baos = new ByteArrayOutputStream();
             PrintStream pw = new PrintStream(baos);
             System.setOut(pw);
             T t = new T();
             t.start();
             t.join();
             System.setOut(save);
             pw.flush();
             System.out.println("from thread: " + baos.toString());
         } catch (InterruptedException e) {
             e.printStackTrace();
         }
     }
}

class T extends Thread {
     public void run() {
         System.out.println("Hello world");
     }
}
