新安裝的jdk12，想試試換個皮膚，提示以上錯誤
附上代碼：
public class One extends JFrame{
public static void main(String[] args)
{
new One();
}
One(){
try {
UIManager
.setLookAndFeel("com.sun.java.swing.plaf.nimbus.NimbusLookAndFeel");
} catch (Exception e) {
e.printStackTrace();
}
this.setSize(1320, 750);
this.setVisible(true);
this.setLocationRelativeTo(null);
this.setDefaultCloseOperation(EXIT_ON_CLOSE);
}
}
