Height of Copy Paste Example.

Java StringBuffer / StringBuilder

It seems the author just copied StringBuffer.java to StringBuilder.java, removing all occurrences of "synchronized".

Here is a little trace left in StringBuilder.readObject method:

/**

* readObject is called to restore the state of the StringBuffer from

* a stream.

*/

private void readObject(java.io.ObjectInputStream s)

throws java.io.IOException, ClassNotFoundException {

s.defaultReadObject();

count = s.readInt();

value = (char[]) s.readObject();

}

//Copy from Javadoc of Stringbuilder class.
