Java Strings are immutable (cannot be changed) so reversing a String requires creating a new String.
A loop can be used to build the reversed string by adding the characters from original string in reverse order, but the StringBuilder class provides a reverse() method to do it for us.
The following example shows its usage.
String s = "The string to be reversed"; StringBuilder sb = new StringBuilder(s); sb.reverse(); String reversed = sb.toString();
