substring

Language/Type: Java Strings
Author: Stuart Reges (on 2020/10/02)

Write a static method substring that accepts a String and two Integers beginIndex and endIndex and 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. 

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