小编slo*_*per的帖子

    String s1 = PasswordText4.getText();
    String s2 = ConfirmText4.getText();
    String s3 = NameText4.getText();
    String s4 = UsernameText4.getText();
    String s5 = jLabel16.getText();

    if (PasswordText4.getText().equals(ConfirmText4.getText()) && s1.length() != 0 && s3.length() != 0 && s1.length() >= 4 && s2.length() >= 4) {
        try {
            String sql
                    = "BEGIN"
                    + "UPDATE LOGIN SET USERNAME = ?, PASSWORD = ?, NAME = ?"
                    + "WHERE USERNAME = ?;"
                    + "commit;"
                    + "END;";
            CallableStatement cstmt = conn.prepareCall(sql);
            cstmt.setString(1, UsernameText4.getText());
            cstmt.setString(2, PasswordText4.getText());
            cstmt.setString(3, NameText4.getText());
            cstmt.setString(4, jLabel16.getText());

            //System.out.println(jLabel16.getText()); …

我试图从下拉列表中获取主题名称和ID的两个值.我将ID设置为选定值,并将主题名称设置为数据字段.

有没有办法可以将这个数据字段转换成文本？

 string subjectName = ddlSubjectName.Text;
 string subjectId =Convert.ToString(ddlSubjectName.SelectedValue);

上面的代码将下拉列表的选定值放入subjectName和subjectId,因为我正在尝试将这两个字段添加到我的sql数据库中

例如,如何转换字符串"Bohinjska ?ešnjica".我从网站获得的字符串,它没有编码unicode.它在使用swing(Netbeans)的程序中工作正常,但是当我通过jar到Windows控制台的链接(运行jframe应用程序)时,它不会在字符串中显示正确"Bohinjska ?ešnjica"的字符'?'和字符'š'.

String example="Bohinjska ?ešnjica";

我从网站上获取该字符串.如何编码或显示,因为它是("Bohinjska ?ešnjica")在一个Swing应用程序,所以当我将运行一个jframe应用程序,它会显示我这个角色(以及其他Unicode字符ofcourse("Z","Z","C"和"S") )？
