Java StringBuffer SubString Example
This example shows how to get a sub string of content of the StringBuffer using
substring method of Java StringBuffer class.

SubString method is overloaded in StringBuffer class
1. String substring(int start)
returns new String which contains sequence of characters contined in
StringBuffer starting from start index to StringBuffer.length() - 1 index

2. String substring(int start, int end)
returns new String which contains sequence of characters contined in

Output would be

Substring 1 : StringBuffer SubString Example
Substring 2 : Java StringBuffer
