Use StringBuffer for string concatenation

Because Java Strings are immutable, usage of the + operator to concatenate strings results in the creation of many temporary objects. Calling explicitely StringBuffer.append eliminates those temporary objects and may result in a large performance increase.

I also tend to believe it is simply more correct to use StringBuffer.append when concatenating strings, rather than the + operator. But maybe your reason is because it's faster than String.+ !

String a = "Das "; // Objekt 1
String b = "ist nicht so gut"; // Objekt 2
a = a + b; // Objekt 3:: hier wird ein neues Objekt erzeugt ! Strings sind unveränderlich (inmutable)

// String Buffer
StringBuffer a = new StringBuffer("Das"); //Objekt 1
String b = "ist meist besser";  //Objekt 2
a.append(b); // Objekt 1 !

Recycling
Java has no knowledge of the heavyweight back-end Domino Objects, only the lightweight Java objects representing them. For local classes, the Domino Objects use memory in the process running the Java program and no garbage collection occurs without recycling until the program exits. Memory use can be problematic for:

    * A program that runs for a long time
      Servlets, especially, fall in this category.
    * A program that iterates over Domino Objects
      Loops that process documents fall in this category.
[...] weiteres sinnvolles Zeug.

schaemt sich da jemand fuer schlechte SW-Architektur???
