Question

In this part of the projectyou wll create a Class representing the extension of a Picture. To accomplish this, you will use a class calfed MyPicture that has a field of type Picture. This field or instance variable will be the basis for your extension. Use the same library library.zip from part 1. The API can be found here. Download the file MyPicture,java and place it inside the library directory. Follow the methods descriptions and write your code inside the methods provided. Submit the file MyPicture.java. Observe the following rules: DO NOT add any import statements to MyPicture.java DO NOT add the project statement to MyPicture,java DO NOT change the headers of ANY of the given methods DO NOT add any new class fields DO NOT use System.exit0) Note1: you have 5 submissions without deductions; 5 points deduction for every submission thereafter.
