/*
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.
*/
public class JavaStringBufferSubStringExample {
public static void main(String[] args) {
//create StringBuffer object
StringBuffer sb = new StringBuffer("Java StringBuffer SubString Example");
System.out.println("Original Text : " + sb);
/*
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
*/
String strPart1 = sb.substring(5);
System.out.println("Substring 1 : " + strPart1);
/*
2. String substring(int start, int end)
returns new String which contains sequence of characters contined in
StringBuffer starting from start index to end index
*/
String strPart2 = sb.substring(0,17);
System.out.println("Substring 2 : " + strPart2);
/* Please note that both the methods can throw a StringIndexOutOfBoundsException
if start or end is invalid.
*/
}
}
/*
Output would be
Original Text : Java StringBuffer SubString Example
Substring 1 : StringBuffer SubString Example
Substring 2 : Java StringBuffer
