ResultSet未返回

Question

即使在使用executeUpdate（）面临同样的问题后，我也得到“查询不返回ResultSet”。我使用过SQlite.i已在此处添加了我的代码

try{
        String str = userid.getText();
        char[] str1 = userpass.getPassword();
        String str2 = Arrays.toString(str1);
        Connection con;
        con = DriverManager.getConnection("jdbc:sqlite:C:/Users/Ajay/AppData/Local/Temp/Rar$EXa0.794/SQLiteStudio/Login");
        Statement stmt;
        stmt = con.createStatement();
        Class.forName("org.sqlite.JDBC");
        String strng = "insert into login(user,password) values('"+str+"','"+str2+"')";
        stmt.executeUpdate(strng);
        con.commit();
        stmt.close();
    }
    catch(Exception e){
        JOptionPane.showMessageDialog(this,e);
    }
