I can not use the "int length" constructor for StringBuilder since the lenght of my CLOB is longer than a "int" and needs a "long" value. I am not that confortable with the Java I/O classes, and would like...

Note: I realize this isn't the best way to...

On the one hand, this would seem the most logical thing. On the other hand, it seems to kind of defeat the purpose of the StringBuilder c...
When I don't include the commented line, prevLineBuffer contains "null." When i do include the commented line it still works, but prints an empty string. Does Java statically allocate space for the declared string and then dynamically allocate space for an additional string in the commented line? Both appear to work... public class Inde...

I've got a chunk of text in a StringBuilder object. I need to replace one substring with another. The StringBuilder Replace method can do this, but it replaces every instance of the substring and I only want to replace the first found instance.
