Computing Distances

Given two points, the formula for computing the distance is

Write a program that prompts the user to enter two points and computes the distance between them. Note that each point is characterized by two float values, representing the x-axis and y-axis.

Sample Run

Enter x1 and y1 for Point 1: 1.5, -3.4

Enter x2 and y2 for Point 2: 4, 5

The distance between (1.5, -3.4) and (4, 5) is 8.8

Explanation / Answer

DistanceTest.java

import java.text.DecimalFormat;

import java.util.Scanner;

public class DistanceTest {

public static void main(String[] args) {

DecimalFormat df = new DecimalFormat("0.00");

Scanner scan = new Scanner(System.in);

System.out.println("Enter x1 and y1 for Point 1:");

float x1 = scan.nextFloat();

float y1 = scan.nextFloat();

System.out.println("Enter x2 and y2 for Point 2:");

float x2 = scan.nextFloat();

float y2 = scan.nextFloat();

float distance = (float)Math.sqrt((x2-x1)*(x2-x1) + (y2-y1)*(y2-y1));

System.out.println("The distance between ("+x1+", "+y1+") and ("+x2+", "+y2+") is "+df.format(distance));

}

}

Output:

Enter x1 and y1 for Point 1:
1.5 -3.4
Enter x2 and y2 for Point 2:
4
5
The distance between (1.5, -3.4) and (4.0, 5.0) is 8.76
