Write a java program to find the distance between two points.

import java.util.Scanner;

class Distance {
    public static void main(String[] args) {
        
        // Scanner class object to read input values
        Scanner sc = new Scanner(System.in);
        
        // declare variables
        int x1, x2, y1, y2, x, y;
        double dist;
        
        // read coordinates from user
        System.out.print("Enter first point coordinates: ");
        x1 = sc.nextInt();
        y1 = sc.nextInt();
        System.out.print("Enter second point coordinates: ");
        x2 = sc.nextInt();
        y2 = sc.nextInt();

        // calculate distance
        x = x2 - x1;
        y = y2 - y1;
        dist = Math.sqrt(x * x + y * y);
        
        // print result
        System.out.println("Distance between two points = " + dist);
    }
}

Output

Enter first point coordinates: 20 15
Enter second point coordinates: 20 32
Distance between two points = 17.0
