•Like a String, but with direct
access to char contents – therefore mutable
•Much more efficient
•
•StringBuffer
buf = new StringBuffer("World");
•buf.insert(0, "Jello, ");
•buf.append("!");
•buf.setCharAt(0,'H'); // now "Hello,
World!"
•buf.reverse(); // now "!dlroW ,olleH"
•String
s = buf.toString();
