substring

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