我之前使用此代码启动了此表单,但在对表单进行了多次编辑后,它将不再启动。有什么建议么?
public static void main(String args[]) {
  try {
    for (javax.swing.UIManager.LookAndFeelInfo info: javax.swing.UIManager.getInstalledLookAndFeels()) {
      if ("Nimbus".equals(info.getName())) {
        javax.swing.UIManager.setLookAndFeel(info.getClassName());
        break;
      }
    }
  } catch (ClassNotFoundException | InstantiationException | IllegalAccessException | javax.swing.UnsupportedLookAndFeelException ex) {
    java.util.logging.Logger.getLogger(Registrar.class.getName()).log(java.util.logging.Level.SEVERE, null, ex);
  }
  //</editor-fold>
  /* Create and display the form */
  java.awt.EventQueue.invokeLater(new Runnable() {
    @Override
    public void run() {
      new Registrar().setVisible(true);
    }
  });
}
