Implement the String Builder class) The StringBuilder class is provided in the Java library. Provide your own implementation for the following methods (name the new class MyStringBuilder1): public MyStringBuilder1(String s); public MyStringBuilder1 append(MyString Builder1 s); public MyStringBuilder1 append(int i); public int length(): public char charAt(int index); public MyStringBuilder1 to LowerCase(): public MyStringBuilder1 substring(int begin, int end); public String toString(): In C++ Implement an immutable Fraction Class described in the readings. Then add the following methods to emulate arithmetic operations and I/O operations on Fractions. 1. Arithmetic operators: +-*/ 2. Relational operators: < >= 3. Equality operators: == != 4. Stream Extraction: >>(i.e. 3/7 form) 5. Stream Insertion: < < (i.e. 3/7 form) 6. Method to reduce fraction 7. Assignment Operator = that evaluates right to left only Demonstrate all capabilities (methods) Implemented. Implement a test program to demonstrate your class methods.
