问题

以下是翻译好的部分：

public class lib {
    public lib() {
        gui();
    }

    int kitapno[] = new int[10];
    int kitapnoindex;
    int quantity[] = new int[10];
    int quantityindex;
    int kitapadetleri;

    public void gui() {
        // ...

        public void actionPerformed(ActionEvent e) {
            String issbookno_string = issbookno_text.getText();
            int issbookno_int = Integer.parseInt(issbookno_string);

            Date pt_issbook = new Date();
            DateFormat ptformat_issbook = new SimpleDateFormat("dd/MM/yyyy hh:mm:ss");

            if (issbookno_string.equals("")) {
                JOptionPane.showMessageDialog(issbook_window, "no way");
            } else {
                for (int i = 0; i < kitapno.length; i++) {
                    if (issbookno_int == kitapno[i]) {
                        row_issue[0] = kitapno[i];
                        row_issue[1] = issstudentid_text.getText();
                        row_issue[2] = issstudentname_text.getText();
                        row_issue[3] = issstudentcontact_text.getText();
                        row_issue[4] = ptformat_issbook.format(pt_issbook);
                        JOptionPane.showMessageDialog(issbook_window, "You have been succesfully issued a book");
                        model_issue.addRow(row_issue);
                    }
                }
            }
        });
    }

if (issbookno_string.equals(""))//如果用户未填写issbook名称
{
    JOptionPane.showMessageDialog(issbook_window, "无方式显示");//显示无方式可显示
}

我不确定这是否是因为格式问题，但是 // 被用作单行注释，这意味着在 if user don't fill out the issbook name 注释中的 name 和在 print no way to display 注释中的 way to display 实际上并没有被注释掉，因为它们与双斜杠位于不同行。为了添加多行注释，你可以使用 /* 将注释括起来。

if(issbookno_string.equals(""))//if user don't fill out the issbook
name
{ JOptionPane.showMessageDialog(issbook_window,"no way");//print no
way to display
}

I'm not sure if this is because of the formatting or not, but ```//``` is used for single line comments, which means the "name" in the "if user don't fill out the issbook name" comment and "way to display" in the "print no way to display" aren't actually being commented, as they are on separate lines from the double slash. In order to add multi line comments, you could enclose the comments with ```/*``` instead.
