It would be convenient to have a method in
StringBuffer:

StringBuffer append(StringBuffer strBuf)

This would allow you to do an append of one
StringBuffer to another without the overhead of
creating a String object. It's annoying that you
have to do this:

bufa.append(bufb.toString());

where bufa and bufb are both StringBuffers.

I guess an equivalent insert method would also be
useful.

orig synopsis: "Lack of an add method for StringBuffer class with StringBuffer as a parameter"

StringBuffer doesn't have an "add" method with StringBuffer as
a parameter. This method could help to "concatenate" one
StringBuffer to another without converting to String or
playing with "char" arrays.

The following is the proposed implementation for this method:

    public synchronized StringBuffer append(StringBuffer strbuf)
    {
      int len = strbuf.length();
      int newcount = count + len;
      if (newcount > value.length)
        expandCapacity(newcount);
      System.arraycopy(strbuf.getValue(), 0, value, count, len);
      count = newcount;
      return this;
    }
