reverse method in JDK6.0

[analoveu]

I want to know if there is a built-in method in the java class library and ready for use .If there how can i use it to reverse a string and print it
I saw i the JDK6.0 Docs this method

java.lang
Class StringBuffer
java.lang.Object
java.lang.StringBuffer

public StringBuffer reverse()
Causes this character sequence to be replaced by the reverse of the sequence

How can I use this method?!

reverse() reverses the order of the characters in the StringBuffer, so it will do what you're looking for.

StringBuffer str = new StringBuffer("This is a string");
System.out.println(str);
str.reverse();
System.out.println(str);
 

This would print:

This is a string
gnirts a si sihT

Consider using the more efficient StringBuilder instead.

String reverse = new StringBuffer("original").reverse().toString();
