AW: Returning an object containing various HTML objects

[Comba-Riepenhausen Enrique (CO)]

I would return them in following format:

public String create questionPanel()
{
    String returnString = "";
    Table firstTable  = new Table();
    Table secondTable = new Table();
    Table thirdTable  = new Table();
       .
       .
       .
     Other Objects.....

      ....add all objects together
    StringBuffer returnString = new StringBuffer();
    returnString.append( firstTable.toString() );
    returnString.append( secondTable.toString() );
    returnString.append( thirdTable.toString() );
    returnString.append( otherObjects.toString() );
     return (returnString.toString() );    
}


This is an performance issue. if you concatenate the String with += 
you spend a lot of time in the creation of a new Object every time.

Or, write them all as Strings and return a string:

public String create questionPanel()
{
    String returnString = "";
    Table firstTable  = new Table();
    Table secondTable = new Table();
    Table thirdTable  = new Table();
       .
       .
       .
     Other Objects.....

      ....add all objects together
    returnString += firstTable.toString();
    returnString += secondTable.toString();
    returnString += thirdTable.toString();
    returnString += otherObjects.toString();
     return (returnString);    
}
