I just programmed my first JFrame and exported it, but I'm not able to run the .jar file normally. When I try to run it using Terminal, it works without any problems. However, when I try to open the file normally by double clicking on it, I get an error message similar to this: The Java jar file "Programm.jar" could not be launched. Here's the code (maybe there's something wrong with it?):
package GUI;
import javax.swing.JFrame;
public class Frame {
public static void main(String[] args) {
JFrame jf = new JFrame();
jf.setVisible(true);
jf.setSize(500, 300);
jf.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
jf.setLocationRelativeTo(null);
jf.setTitle("Programm");
jf.setResizable(false);
}
}
Thanks in advance!
