Java Make Own System.out

Question

Is there any way to make my own System.out? I want to have a class "MyConsole" with an attribute out (PrintWriter) and send from all classes txt messages that will be printed in a JTextArea (like System.out print all messages in the console) without make a instance of it in all classes or pass it in the attributes

Answer 1

Create a static final class and static methods and use it through out the application. Static method can be directly called without instantiating the class.

Answer 2

i need something like ex: Console1.out.println(message1) and the message 1 goes only in the JTextArea linked Console1, Console2.out.println(message2) and the message 2 goes only in the JTextArea linked Console2

Why don't you just make your own class that extends JTextArea and write a method to do what you want? Something like:

public class MyTextArea extends JTextArea {
    public void println() {
        //add text to the textarea
    }
}

If you don't need your method to have name println you can just use the append method, which already exists in the JTextArea:

textArea.append(myString+"\n");

Answer 3

I use this open source Message Console in java. It's simple to use.
