StringBuilderDemo.java
/*
* public int lastIndexOf(String str)
*
* Parameters:
* ----------
* str - the substring to search for.
*
* Returns:
* -------
* if the string argument occurs one or
* more times as a substring within this object, then
* the index of the first character of the last such
* substring is returned. If it does not occur as a
* substring, -1 is returned.
*/

public class StringBuilderDemo
{

public static void main(String[] args)
{
String str = "Welcome.com";
StringBuilder sb = new StringBuilder(str);
System.out.println("sb = "+sb);

//Returns 8
int indexPosition = sb.lastIndexOf("com");
System.out.println("lastIndexOf(\"com\") = " + indexPosition);

indexPosition = sb.lastIndexOf("abc");
System.out.println("lastIndexOf(\"abc\") = " + indexPosition);
}
}
Output
sb = Welcome.com
lastIndexOf("com") = 8
lastIndexOf("abc") = -1
