2.15 (Geometry: distance of two points) Write a program that prompts the user to enter two points (x1, y1) and (x2, y2) and displays their distance between them. The formula for computing the distance is √(x2-x1)2+(y2-y1)2 Note that you can use Math.pow(a, 0.5) to compute 2a. Here is a sample run:
Enter x1 and y1: 1.5 -3.4
Enter x2 and y2: 4 5
The distance between the two points is 8.764131445842194
Enter x1 and y1: 1.5 -3.4
Enter x2 and y2: 4 5
The distance between the two points is 8.764131445842194
import java.util.Scanner; public class ProgrammingEx2_15 { public static void main(String[] args) { Scanner input = new Scanner(System.in); System.out.print("Enter x1 and y1:"); double x1 = input.nextDouble(); double y1 = input.nextDouble(); System.out.print("Enter x2 and y2:"); double x2 = input.nextDouble(); double y2 = input.nextDouble(); double distance = Math.sqrt(Math.pow((x2 - x1), 2) + Math.pow((y2 - y1), 2)); System.out.print("The distance between the two points is " + distance); } }
