当我将一个java字符串传递回我的servlet时,servlet将该字符串传递给jsp.

该字符串用新行"\n"保存名称和地址,但是当我试图在屏幕上显示时,我看到一个完整的行,但是在控制台上显示了新行.

这是一个快照: 首先 第二 第三:来自CONSOLE

知道如何解决这个问题吗？

我想5在名为的表中更新用户个人信息的字段Personnel-table.

用户可能希望更新所有字段,部分字段或根本不更新.

用户可能要更新的字段有:FirstName,LastName,Password,UserName 和Address.

该代码执行此操作:

public boolean updateUserInfo(String _idnumber , String _usernameNew , String _passwordNew ,  
        String _addressNew , String _firstNameNew , String _lastNameNew) throws SQLException
{

    ResultSet resultSet = null;

    String sqlStatement = "UPDATE PersonnelTable set `UserName` = ? WHERE `IdNumber` = ?";
    this.m_prepared = (PreparedStatement) this.m_connection.prepareStatement(sqlStatement);
    this.m_prepared.executeUpdate("USE Personnel");

    // set the ID number & account number 


    /**
     *  first 
     */
    m_prepared.setString(1, _usernameNew);
    m_prepared.setString(2, _idnumber);

    // …

考虑一下代码:

private String mode;        // current played mode

private void func(int row , int column)
{
    // rotation mode 
    if ((row == 0 && column == 0) || (row == 2 && column == 0) || (row == 0 && column == 2) || (row == 2 && column == 2)) 
    {
        mode = ROTATE_MODE;
    }

    // scaling more 
    else if ((row == 0 && column == 1) || (row == 1 && column == 0) || (row == 2 …

我想从PersonnelTable以下方式调用的表中删除:

public void verifyDetailsBeforeClosingAccount(String _idNumber,String _username,String _password ,String _account)
{

    String retrievedNumberAccount = null;
    String retrievedOwnerIdnumber = null;

    try
    {

        // take all the rows with "account-number" and "id-numbder" in the "Checking-account-table" 

        ResultSet results = this.m_statement.executeQuery("SELECT `AccountNumber`, `IdNumber`  FROM `CheckingAccountsTable`");  
        while (results.next() == true)
        {
            retrievedNumberAccount = results.getString("AccountNumber");  // take the account number 
            retrievedOwnerIdnumber = results.getString("IdNumber");       // take the ID number 

            if (retrievedNumberAccount.equals(_account) == true && retrievedOwnerIdnumber.equals(_idNumber) == true )  // found a partial match 
            {
                // put …

以下是什么意思？

find myDirectory -name myFile -exec ls \-ln {} \; 

我看过这里,但并不完全明白

-exec command   True if the executed command returns a zero value as exit status. The end of command must be punctuated by an escaped semicolon. A command argument {} is replaced by the current path name.

这部分-exec ls \-ln {} \;对我来说并不清楚.
