import java.util.Scanner;

public class ReadArrayElements {

// The main() method is the entry point of every Java application.

public static void main(String[] args) {

// Create a Scanner object to read input from the keyboard.

Scanner scanner = new Scanner(System.in);

// Ask the user to enter the size of the array.

System.out.print("Enter the Size of the Array: ");

// Read the size entered by the user.

int size = scanner.nextInt();

// Check whether the entered size is valid.

if (size <= 0) {

// Display an error message.

System.out.println("Please enter a positive array size.");

} else {

// Declare a one-dimensional integer array.

int[] array = new int[size];

// Ask the user to enter the array elements.

System.out.println("Enter " + size + " Array Elements:");

// Read and store each array element.

for (int i = 0; i < size; i++) {

// Read the current element from the user.

array[i] = scanner.nextInt();

}

// Display a success message.

System.out.println("Array elements have been read successfully.");

// Example Output:

// Enter the Size of the Array: 5

// Enter 5 Array Elements:

// 10

// 20

// 30

// 40

// 50

// Array elements have been read successfully.

}

// Close the Scanner object to release system resources.

scanner.close();
