Apply Syntheticablackeyelookandfeel to the application

Question

I would like to know how I can apply new look and Feels that are not part of JDK. In trying to apply, is giving an error in which I did not find an answer that could solve the problem.

For example: The Synthetica Classy Look and Feel:

Test Class:

import de.javasoft.plaf.synthetica.SyntheticaBlackEyeLookAndFeel;
import java.text.ParseException;
import java.util.logging.Level;
import java.util.logging.Logger;
import javax.swing.JOptionPane;
import javax.swing.UIManager;
import javax.swing.UnsupportedLookAndFeelException;

public class JavaApplication12 {

/**
 * @param args the command line arguments
 */
public static void main(String[] args) {
    try {
        UIManager.setLookAndFeel(new SyntheticaBlackEyeLookAndFeel());
    } catch (UnsupportedLookAndFeelException | ParseException ex) {
        Logger.getLogger(JavaApplication12.class.getName()).log(Level.SEVERE, null, ex);
    }        
    JOptionPane.showMessageDialog(null, "Teste");
}

}

Error description:

Reference to setLookAndFeel is ambiguous Both method setLookAndFeel(Lookandfeel) in Uimanager and method setLookAndFeel(String) in Uimanager match

Answer 1

According to the official website and how it can be seen in this answer, the correct way to apply is as follows:

try {

  UIManager.setLookAndFeel("de.javasoft.plaf.synthetica.SyntheticaBlackEyeLookAndFeel");

} catch (Exception e) {

  e.printStackTrace();

}

Remembering that one should also add the synthetica. in the classpath, in addition to the downloaded theme jar (in your case, the syntheticaBlackEye.jar) before making this call, as can be seen below in the example print:
