In today's digital age, generating random lottery numbers is a common task that combines the use of Java's Math methods and array handling. This paper explores the development of a Java program that creates four unique random numbers within the range of 1 to 99, suitable for lottery selections. The program demonstrates fundamental programming concepts including randomness generation, array management, and formatted output, essential for novice programmers to understand. The core of the program relies on the Math.random() method, which produces a double value between 0.0 (inclusive) and 1.0 (exclusive). To transform this into integers within a specific range, Math.ceil() is used after multiplying the result of Math.random() by 99. This operation ensures the numbers are rounded up to the nearest integer, resulting in a range from 1 to 99. The process is repeated to generate four individual numbers, each stored within an array for subsequent processing. Generating unique lottery numbers is crucial to mimic real-world scenarios where duplicate numbers are typically avoided. To achieve this, the program initializes an array with zeros indicating that no numbers have been assigned yet. As each random number is generated, the program checks if it already exists in the array to prevent duplicates. If the number is new, it is stored in the first available zero position; otherwise, the process repeats until four unique numbers are obtained. The design employs a for loop to control the number of generated lottery numbers. During each iteration, a new random number is produced and inserted into the array if it doesn't already exist within it. Once all four numbers are ready, the program outputs the numbers in a formatted string, clearly indicating the winning numbers for the user. Commenting the code enhances readability and maintainability. Each step, from generating random numbers to array management and output formatting, is explained within comments.
