MyStringTest.java

/* Exercise 10.22 & 10.23

 * (Implement the String class) The String class is provided in the Java library.
Provide your own implementation for the following methods (name the new class MyString1 ):
public MyString1(char[] chars);
public char charAt(int index);
public int length();
public MyString1 substring(int begin, int end);
public MyString1 toLowerCase();
public boolean equals(MyString1 s);
public static MyString1 valueOf(int i)

Provide your own implementation for the following methods (name the new class MyString2 ):
public MyString2(String s);
public int compare(String s);
public MyString2 substring(int begin);
public MyString2 toUpperCase();
public char[] toChars();
public static MyString2 valueOf(boolean b);
 * Implement the requirements for both MyString1 and MyString2 as a single class, MyString.
As well as implementing the MyString class, provide a test main method in the main class MyStringTest that demonstrates the use of your class and its methods.
Have all your classes inside one .java file, MyStringTest.java. Do not have a separate file for the MyString class.
