Efficient text manipulation...

If I got a String or a StringBuffer for example :
StringBuffer s = new StringBuffer();

s = "Hello World! Whats up?";

What is an efficient way to get the 1st word ("Hello") - save it and then to cut it from the string so all that is left is : " World! Whats up?"

Thanks for the help in advanced guys

Use StringTokenizer or split() method.

Depends on how the splitting si to be acheived -- the split() could be very annoying. If we assume that words are separated by spaces, then a simple indexOf(' ') and then substring would work nicely:

My take was that the main question was how to remove "Hello" .. not just get that string.StringBuffer.delete() will result in an array copy to shift the text after the removed portion.
I agree. Here's the link:
