我正在做一个写入 sql 数据库的项目。我现在的问题是我不知道如何在一个程序中创建多个表单。我正在使用 JGrasp 编写程序。
我得到的错误是在我尝试添加第二种形式之后。它说：
StartMenuOptions.java:126：错误：此处不允许修饰符 private
我的代码包括在下面：
public class StartMenuOptions extends javax.swing.JFrame {
/**
* Creates new form StartMenuOptions
*/
public StartMenuOptions() {
initComponents();
}
/**
* This method is called from within the constructor to initialize the form.
* WARNING: Do NOT modify this code. The content of this method is always
* regenerated by the Form Editor.
