Eclipse令牌"}“上的语法错误，删除此令牌和语法错误，插入"}”以完成ClassBody

Question

我试图为书店职员制作一个实践程序，允许书记员在其数据库中添加、删除、编辑和搜索书籍。我已经做了整个程序，但我被困在两个错误。总共有234行代码，所以我会尽量把它缩短到相关部分，让那些愿意帮助我的人更容易。据我所知，Eclipse与JDE和JDK 10一起使用Eclipse，Eclipse项目是使用JavaSE-10执行环境启动的。下面是导致错误的两个方法。

public class Bookstore {

    public static void main(String[] args) {
        try(
                //Creating table connection and statement
                Connection conn = DriverManager.getConnection("***********",
                        "****", "*********"); //Please note that I blocked out the actual connection information here

                Statement stmt = conn.createStatement();
                ){

            Scanner input = new Scanner(System.in);
            int selection = 0;

            //Menu for action selection and user input
            while(selection != 5) {
                System.out.println("Please enter the number corresponding to the action you would like to take:\n"
                        + "1. Enter book\n"
                        + "2. Update book\n"
                        + "3. Delete book\n"
                        + "4. Search books\n"
                        + "5. Exit");
                selection = input.nextInt();

                //Selection sorting
                if(selection == 1) {
                    //Collecting book information
                    System.out.println("Please enter the Title of the book you would like to put into the system: ");
                    String title = input.next();
                    System.out.println("Please enter the Author of said book: ");
                    String author = input.next();
                    System.out.println("Please enter the number of said book currently in stock: ");
                    int qty = input.nextInt();

                    //Sending info to the addBook method
                    addBook(title, author, qty, stmt);
                } else if(selection == 2) {
                    //Collecting book information
                    System.out.println("Please enter the id of the book you would like to update: ");
                    int id = input.nextInt();

                    //Sending info to the updateBook method
                    updateBook(id, stmt);
                } else if(selection == 3) {
                    //Collecting book information
                    System.out.print("Please enter the id of the book you would like to delete from the system: ");
                    int id = input.nextInt();

                    //Sending info to deleteBook method
                    deleteBook(id, stmt);
                } else if(selection == 4) {
                    searchStore(stmt);
                } else if(selection == 5) {
                    System.out.println("Goodbye");
                    input.close();
                } else { //Invalid entry handler
                    System.out.println("Sorry, that isn't a valid selection.");
                }
            }

        } catch(SQLException ex) {
            ex.printStackTrace();
        }
    }
} //This is the line giving me the error "Syntax error on token "}", delete this token"

现在，我已经对这个代码块底部的错误进行了一些研究。据我所知，我没有遗漏任何括号，也没有在类之外创建变量或任何东西会导致此错误。我唯一能找到的其他解决方案是"Eclipse只是有点奇怪“。

我的第二个错误来自于这段代码：

public static void resultSetPrinter(ResultSet rset) {
    while(rset.next()) {
        String title = rset.getString("Title");
        String author = rset.getString("Author");
        int qty = rset.getInt("qty");
        System.out.println("Title: " + title + "\nAuthor: " + author + "\nNumber in stock: " + qty + "\n\n");
    }
    if(rset == null) {
        System.out.println("No records for the entry could be found.");
    }
} //This is the line giving me the "Syntax error, insert "}" to complete ClassBody" error

我还对这个块底部的错误做了一些研究，当我按要求删除括号时，错误就跳到前面的方法。在这个类中，我没有包括其他4种方法，因为它们不会给我带来错误，所以我没有尝试减少运行所有这些代码所带来的麻烦。在这一点上，任何帮助都将是非常感谢的，我完全感到困惑。

Answer 1

主要感谢埃利奥特·弗里斯，我找到了答案。本质上，我需要将我的所有方法以Bookstore的名字放入我的主类中。我将}移到程序的末尾，并为每个方法添加了try catch语句。例如，我将问题中的最后一个代码块更改为：

public static void resultSetPrinter(ResultSet rset) {
    try {
        if(rset.next()) {
            while(rset.next()) {
                String title = rset.getString("Title");
                String author = rset.getString("Author");
                int qty = rset.getInt("Qty");
                System.out.println("Title: " + title + "\nAuthor: " + author + "\nNumber in stock: " + qty + "\n");
            }
        } else {
            System.out.println("No records for the entry could be found.\n");
        }
    } catch(SQLException ex) {
        ex.printStackTrace();
    }
}

您还将注意到，我添加了一个if rset语句，以检查rset是否为空，如果不是，则按正常方式进行，如果是，则打印一条简单的消息，让用户知道什么都没有找到。

谢谢你们两位埃利奥特·弗里斯和Marco13的支持。
