How to print color in console using System.out.println?
(15 answers)
Closed 3 years ago.
How do I make this output "Make this a different color", but in red? In Java.
Sorry for stupid question
System.out.println("Make this a different color");
Try this
System.out.println("\033[0;31m Make this a different color");
I think you can't do it in Java if you are printing to the console.

Getting active window information in Java

I'm trying to get the state of a window on Windows. I have to check if the window of word is active or inactive. I don't find any answer to this problem in Google.
Does anyone knows how to do this or if this is possible at all?
Window activeWindow = javax.swing.FocusManager.getCurrentManager().getActiveWindow();
The code above returns always NULL.
Thank you for your answers.
Regards
Roman
Try to use frame.hasFocus() or frame.isFocusOwner()

There is no way to block CTRL+ALT+DELETE. In any way, shape or form. It is an absolute guarantee against hacking.

How would I make a pop up box/A dialog window in Java? For instance say I want to make a window saying "Hello My name is John Smith". How would I do that? Would I have to use swing?
Yes, use Swing by simply using a Swing javax.swing.JOptionPane.
JOptionPane.showMessageDialg(null, "hello world");
