Example: Determine Quadrant of Coordinates in Java

// Determine Quadrant of Coordinates
import java.util.Scanner;

// Main class containing the entry point of the program
public class Main {
    public static void main(String[] args) {
        // Step 1: Create a Scanner object to read user input
        Scanner scanner = new Scanner(System.in);

        // Step 2: Prompt the user to enter the x-coordinate
        System.out.print("Enter the x-coordinate: ");
        double x = scanner.nextDouble();

        // Step 3: Prompt the user to enter the y-coordinate
        System.out.print("Enter the y-coordinate: ");
        double y = scanner.nextDouble();

        // Step 4: Determine the quadrant or position of the point
        String result;
        if (x == 0 && y == 0) {
            result = "The point (" + x + ", " + y + ") is at the Origin.";
        } else if (x == 0) {
            result = "The point (" + x + ", " + y + ") lies on the Y-axis.";
        } else if (y == 0) {
            result = "The point (" + x + ", " + y + ") lies on the X-axis.";
        } else if (x > 0 && y > 0) {
            result = "The point (" + x + ", " + y + ") lies in Quadrant I.";
        } else if (x < 0 && y > 0) {
            result = "The point (" + x + ", " + y + ") lies in Quadrant II.";
        } else if (x < 0 && y < 0) {
            result = "The point (" + x + ", " + y + ") lies in Quadrant III.";
        } else { // x > 0 && y < 0
            result = "The point (" + x + ", " + y + ") lies in Quadrant IV.";
        }

        // Step 5: Print the determined position
        System.out.println(result);

        // Step 6: Close the scanner
        scanner.close();
