In this post, we will see how to implement distance formula between two points in java.
Formula to find distance between two points ( x1, y1) and (x2 , y2) is
d= sqrt( (x2-x1)^2+ (y2 – y1)^2)
Here is simple program to calculate distance between two points in java.

package org.arpit.java2blog; public class calculateDistanceMain { public static void main(String[] args) { calcualteDistanceMain cdm=new calcualteDistanceMain(); double x1 = 8; double y1 = 5; double x2 = 4; double y2 = 8; double distance = cdm.getDistanceBetweenPoints(x1, y1, x2, y2); System.out.println("Distance : "+distance); } public double getDistanceBetweenPoints( double x1, double y1, double x2, double y2) { return Math.sqrt((x2 - x1) * (x2 - x1) + (y2 - y1) * (y2 - y1)); } } |
Here we have used math.sqrt to calculate square root.
When you run above program, you will get below output:
Distance : 5.0
That’s about how to implement distance formula in java.
