我是Java新手，我也是这个网站的新手，所以如果错误很明显，我很抱歉，但我有一个错误，我不知道它意味着什么，我已经尽力修复它。
我目前正在写一个基本的应用程序库，有一些摇摆界面，但问题是当试图创建一个图书形式的窗口时，有相关的代码。
这是主要窗口。
public class VentanaPrincipal extends javax.swing.JFrame {
public VentanaPrincipal() {
initComponents();
this.setLocationRelativeTo(null);
}
private void bt_salirActionPerformed(java.awt.event.ActionEvent evt) {
// TODO add your handling code here:
EscribirBinario escritor = new EscribirBinario();
// Collections.sort(ListaClientes.clientes);
if (escritor.abrir(Main.archivo1)) {
for (int indice = 0; indice < ListaClientes.clientes.size(); indice++) {
escritor.escribir(ListaClientes.clientes.get(indice));
}
escritor.cerrar();
}
System.exit(0);
}
private void bt_clienteActionPerformed(java.awt.event.ActionEvent evt) {
MantenimientoCliente clientes = new MantenimientoCliente(this, true);
clientes.setVisible(true);
}
private void bt_libroActionPerformed(java.awt.event.ActionEvent evt) {
MantenimientoLibro book = new MantenimientoLibro(this, true);
book.setVisible(true);
}
}
书的形式有代码。
public class MantenimientoLibro extends javax.swing.JDialog {
public MantenimientoLibro() {
}
public MantenimientoLibro(java.awt.Frame parent, boolean modal) {
super(parent, modal);
initComponents();
this.setLocationRelativeTo(null);
}
public MantenimientoLibro(java.awt.Dialog parent, boolean modal) {
super(parent, modal);
initComponents();
this.setLocationRelativeTo(null);
}
private void bt_salirActionPerformed(java.awt.event.ActionEvent evt) {
// TODO add your handling code here:
this.dispose();
}
private void bt_insertarActionPerformed(java.awt.event.ActionEvent evt) {
// TODO add your handling code here:
FormularioLibro formulario = new FormularioLibro(this, true);
formulario.setVisible(true);
this.dispose();
}
}
这就是我得到的错误：

请查看此处的错误报告。它可以解决您的问题：
From the nbusers mailing list I got the following hint:
"workaround it by deselecting 'Compile On Save' in the project options".
马克在评论中指出的答案也是一样的。以下是链接：java.lang.RuntimeException：不可执行的源代码-是什么原因导致的？
退出Netbeans并再次启动compilar解决了问题。
