class MarbleJar
{
public:
   MarbleJar(int black, int white);  // initializes jar contents
   String DrawMarble ( );          // draws and returns color
   void AddMarble (String color);  // adds marble to jar
   Boolean IsEmpty ( );                 // returns true if empty
private:
   int myNumberBlack, myNumberWhite; // marbles in the jar
   int myRandom ( );                 // random number generator

Analysis
In this problem you will have to modify the class marbles.java. Copy this file to your directory and rename it mymarbl.java. Write an additional construct to accept three parameters. Will you have to modify any functions? If you do, be sure that your Lab A still works correctly when you call mymarbl.java instead of marbles.java. Now, modify your client LabA, renaming it as lab C, to draw three marbles at a time, compare, and tabulate results.
