Thank you for your submission! While your code is on the right track, there are a few critical issues that need to be addressed before it can be approved:
-
Incorrect Use of Color Class: The
Ballclass should use the customColorenum instead ofjava.awt.Color. This is crucial to meet the task requirements. -
Random Color and Number Generation: The
Randomobject is incorrectly initialized with a seed in bothColorSupplierandLotteryclasses. Instead, userandom.nextInt()with the appropriate bounds to generate random values correctly. -
Efficiency in ColorSupplier Usage: The
Lotteryclass should reuse a single instance ofColorSupplierrather than creating a new one each timegetRandomBall()is called. -
Missing Main Method: A
main()method is needed to test the functionality by creating and printing three randomBallobjects.
Please address these issues to ensure your code meets the core requirements. Keep up the good work, and I'm confident you'll get it right with these adjustments! 😊

The Random constructor should not take an argument. Instead, use random.nextInt(Color.values().length) to ensure the random index is within the bounds of the Color array.

The random.nextInt() method should be called with an argument specifying the upper bound. Use random.nextInt(Color.values().length) to get a valid index for the Color.values() array.

The Random constructor should not take an argument. Instead, use random.nextInt(100) to generate a random number between 0 and 99, or specify another range if needed.

The random.nextInt() method should be called with an argument specifying the upper bound. Use random.nextInt(100) to ensure the random number is within the desired range.

Great job on making significant improvements to your code! 🎉 You've successfully implemented the main method in the Application class and correctly used the custom Color enum in the Ball class. However, there are a few critical issues that need attention:
-
Random Color Generation: In the
ColorSupplierclass, ensure theRandomobject is initialized without a seed and userandom.nextInt(Color.values().length)to select a valid color index. -
Random Number Generation: In the
Lotteryclass, userandom.nextInt(101)to generate numbers between 0 and 100 inclusive, aligning with task requirements.
These adjustments are crucial for the functionality of your code. Addressing them will enhance your understanding and help you avoid similar issues in the future. Keep up the good work and continue learning from these experiences! 🚀

The Random object should not be initialized with a seed. Instead, use Random random = new Random(); and modify random.nextInt() to random.nextInt(Color.values().length) to ensure it selects a valid index within the bounds of the Color enum.

| ball.setNumber(random.nextInt(100)); |

The Random object is correctly used without a seed, and random.nextInt(100) is appropriate for generating a random number. Ensure that this logic meets the task requirements for the range of random numbers.
