JOptionPane Gui displays wrong fonts

d0a5fdb0-9baa-4be9-b9fd-0717d4abcd8e

I am new to Java Gui programming and have encountered a technical glitch.

I have attached a screen shot which is the output of a very simple program Hello world file that utilizes the JOptionpane .

This example that i have compiled in both Eclipse and the command line and encountered the same result.

Has anyone come across this problem and is there a quick fix?

I also reinstalled JDK checking for corruption, but without success.

Is there a way to retrieve system data which tells me where the GUI is getting its font configurations?

Any assistance is greatly appreciated.

It looks like you have problems with encoding or it is an English text?

You can learn fonts from posts:

java - Setting the Default Font of Swing Program - Stack Overflow

and many others

RuGI:.

Is more of a LOCALE topic.

The machine has a default language other than English, or, when you start the application, one is set.

JOption pane accepts not only strings but also components. Create a label set its font and use it as message.

JLabel label = new JLabel("MESSAGE");

label.setFont(new Font("Arial", Font.BOLD, 18));

JOptionPane.showMessageDialog(null,label,"ERROR",JOptionPane.WARNING_MESSAGE);
