Develop a program which allows the user to enter numbers into an array. Input will be as follows: The user will enter the total number of integers to be entered into the array. The user will then enter that number of unique integers (negative or positive). Do not allow the number of values entered to exceed the array size. Develop methods (SIX) including: The ‘main’ method Print the array Sort the array ( YOU MUST DEVELOP YOUR OWN SORT METHOD – don’t use the API classes) Determine the highest value Determine the lowest value Calculate the average value (double)

The objective of this programming assignment is to develop a Java application that facilitates user input of integers into an array, performs sorting, and computes various statistical measures without relying on built-in Java API sorting methods. This task not only enhances understanding of array manipulations but also solidifies foundational programming skills, including method creation, control structures, and user interaction.

The program begins by prompting the user to specify the total number of integers they intend to enter. This input determines the size of the array that will hold these integers. To ensure data integrity, the program verifies that the number of integers entered does not surpass the predefined array size. Once the size is established, the application uses a loop to prompt the user for each integer individually, confirming the uniqueness of each input to avoid duplicates. This process involves storing each input in the array at the corresponding index.

After populating the array, the program calls a dedicated method to print the array's contents to the console. This method iterates through the array and displays each element in a readable format. Next, the program sorts the array using a custom implementation of a sorting algorithm—such as a bubble sort, selection sort, or insertion sort—since the instructions explicitly prohibit using Java API sorting classes or methods. The sorting method processes the array in place to order the elements from smallest to largest.

Following the sorting process, the program prints the sorted array to allow users to verify the change in order. The subsequent steps involve calculating and displaying statistical measures: the highest and lowest values within the array, and the average value represented as a double precision number. Each of these computations is handled through separate methods, which traverse the array to identify maximum and minimum values, and sum all elements before dividing by the total count to compute the average.

Throughout the implementation, good programming practices such as method encapsulation, input validation, and clear output formatting are emphasized. The modular design ensures each task (printing, sorting, finding extrema, calculating average) is encapsulated within its own method, improving code readability and maintainability.

In conclusion, this program demonstrates key array operations and algorithm development in Java, reinforcing core programming concepts while adhering to constraints that encourage manual implementation of sorting algorithms. By completing this assignment, students develop a deeper understanding of data handling, algorithm design, and user interface in Java programs.
