Thank you for your submission! 🎉 Your code has been reviewed and is approved to help you move forward with your learning journey. However, there are some important points to address:
-
BallClass:- The
toString()method should return a string representation of the ball that includes both the actual color and the number. Replace'color'with the actual color value from theColorsenum.
- The
-
Naming Conventions:
- Ensure variable names follow Java naming conventions. For instance, variables like
Ball,Ball1,Ball2,Ball3, andColorsSuppliershould be renamed toball,ball1,ball2,ball3, andcolorSupplierrespectively, using camelCase.
- Ensure variable names follow Java naming conventions. For instance, variables like
-
LotteryClass:- Avoid using static methods like
getRandomBall()unless necessary. Consider creating an instance of the class instead. - Ensure variable names like
numbandBallstart with a lowercase letter.
- Avoid using static methods like
-
ColorSupplierClass:- Optimize the
getRandomColor()method by creating a singleRandominstance at the class level instead of creating a new one each time the method is called.
- Optimize the
-
ColorsEnum:- Enum values should be in uppercase to follow Java conventions for constants.
These improvements will enhance the readability and efficiency of your code. Keep up the great work, and continue to learn from these suggestions to refine your coding skills! 🚀

The toString method should return a string that includes the actual color of the ball. Replace 'color' with color to use the Colors enum value, and consider adding a space or other separator between 'Ball', the color, and the number for better readability.

Thank you for your submission! 🎉 While your code is mostly well-implemented, there are a few areas that need improvement to fully meet the task requirements:
-
Ball Class:
- The
toString()method is not correctly implemented. It should return a string that includes both the color and number of the ball. Consider using:return "Ball: " + this.color + " " + this.number;.
- The
-
Lottery Class:
- Avoid using static methods like
getRandomBall(). It's recommended to instantiate objects instead. - Ensure variable names follow Java naming conventions. For instance,
ColorsSuppliershould becolorSupplier.
- Avoid using static methods like
-
ColorSupplier Class:
- Instead of creating a new
Randomobject each timegetRandomColor()is called, consider creating a singleRandominstance at the class level for efficiency.
- Instead of creating a new
-
Main Class:
- The
Ballinstances should not be created using static methods. Adjust this to align with best practices. - Ensure variable names like
Ball1,Ball2, andBall3start with a lowercase letter, e.g.,ball1,ball2,ball3.
- The
-
General Issues:
- Make sure all classes, fields, constructors, and methods have explicit access modifiers.
- Enum values in
Colorsshould be in uppercase to follow Java naming conventions for constants.
Despite these issues, your effort is commendable, and the decision to approve is made to help you progress in your learning journey. Please review the comments and address these points in future submissions to enhance your coding skills. Keep up the good work and continue improving! 🚀

The toString method does not correctly concatenate the color and number fields. It currently returns the string 'Ballcolor' followed by the number. You should use this.color and this.number to properly include the object's fields in the returned string. Consider using: return "Ball: " + this.color + " " + this.number;
