public String substring (int beginIndex, int endIndex)

Returns a new string that is a substring of this string. The substring begins at the specified beginIndex and extends to the character at index endIndex - 1. Thus the length of the substring is endIndex-beginIndex.

Examples:

 "hamburger".substring(4, 8) returns "urge"
 "smiles".substring(1, 5) returns "mile"
 

Parameters:

beginIndex		the beginning index, inclusive.
endIndex		the ending index, exclusive.

Returns:  the specified substring.

Exceptions:

IndexOutOfBoundsException

if the beginIndex is negative, or endIndex is larger than the length of this String object, or beginIndex is larger than endIndex.
