Java Program to Find the Distance between Two Points

In this tutorial, we will write a program to find the distance between two given points in java. Before that, you should have knowledge of the following topic in Java.

• Operator in Java

Distance Formula:

The distance between two coordinates or points is calculated using the following formula.

First point: (x₁, y₁)
Second point: (x₂, y₂)
Distance (MN): √((x₂ – x₁)² + (y₂ -y₁)²)

Here x1, y1 are the coordinates of the first point and x2, y2 are the coordinates of the second point. These points indicate the x-axis and y-axis values.

Example:

First Points: (4, 8)
Seecond Points: (12, 14)
Then distance between them √((12-4)² + (14-8)²) = √(64 + 36) = √(100) = 10

Java Program to Find the Distance between Two Points

import java.util.Scanner;

public class Main
{
  public static void main(String[] args)
  {
    Scanner scan = new Scanner(System.in);

    int x1, x2, y1, y2, x, y;
    double distance;

    System.out.println("Enter first coordinates (x1, y1): ");
    x1 = scan.nextInt();
    y1 = scan.nextInt();

    System.out.println("Enter second coordinates (x2, y2): ");
    x2 = scan.nextInt();
    y2 = scan.nextInt();

    //calculation
    x = x2 - x1;
    y = y2 - y1;
    distance = Math.sqrt(x * x + y * y);

    System.out.println("Distance between the two coordinates: " + distance);
  }
}

Output:

Enter first coordinates (x1, y1):
5
3
Enter second coordinates (x2, y2):
2
3
Distance between the two coordinates: 3.0
