I have a function to update the user's information as follows:

public void updateAccount(String username, String name, String address, String aboutMe, String 
id) {
    String sql = "update Account set username = '?', \n"
            + "                [Full_Name] = '?',\n"
            + "                [Address] = '?',\n"
            + "                [about_me] = '?'\n"
            + "                where id = ?";
    try {
        PreparedStatement ps = connection.prepareStatement(sql);
        ps.setString(1, username);
        ps.setString(2, name);
        ps.setString(3, address);
        ps.setString(4, aboutMe);
        ps.setString(5, id);
        ps.executeUpdate();

    } catch (Exception ex) {
        Logger.getLogger(AccountDao.class.getName()).log(Level.SEVERE, null, ex);
    }
}

and this code is giving me an error like this: 

Severe: com.microsoft.sqlserver.jdbc.SQLServerException: The index 2 is out of range.

at dao.AccountDao.updateAccount(AccountDao.java:117)
at controller.UserProfileController.doPost(UserProfileController.java:91)

I don’t understand why it gives me the error "The index 2 is out of range" and is there any
way to fix it?

>Solution :

Don’t enclose ? parameter markers in quotes. These are typed by the appropriate setter:

String sql = "update Account set username = ?, \n"
        + "                [Full_Name] = ?,\n"
        + "                [Address] = ?,\n"
        + "                [about_me] = ?\n"
        + "                where id = ?";
