1. Implement your own String2 class named MyString2 as specified in the attached UML diagram . The String class is provided in the Java library (https://docs.oracle.com/javase/7/docs/api/java/lang/String.html ). Provide your own implementation for the methods listed in the attached MyString1UML diagram below. 2. Use the attached driver to invoke and test MyString2 methods. 3. Make sure your classes and methods are well documented, structured, aligned, and indented

MyString2 -buffer: char D +MyString2 (s: String) Class name One- dimensional array to hold the string- Constructor. It uses the string size to create the buffer array and it copies the chars in the string to buffer.. +MyString2(s: charl) Constructor. It copies the chars in s into buffer. +compare (s: MyString2): int It compares strings with the characters in buffer and returns -1 if first string comes first, o, if they are identical, +1 if first string is higher than second string.- +charAt index: int):char- It returns the char at location index in the buffer. +substring (start: int, end: int):String It copies the substring characters from start to end-1 position in string and returns that string the characters from start to end -1. +substring (begin: int String It copies the substring characters from start to end of string to a string and returns that string.- +toUpperCase():MyString2 It converts the characters in buffer to upper case using Character.toUpperCase(c: char) method.
