BJP5 Exercise 3.11: distance

Language/Type: Java Math method basics parameters return
Author: Marty Stepp (on 2019/09/19)

Write a method called distance that accepts four integer coordinates x1, y1, x2, and y2 as parameters and computes the distance between points (x1, y1) and (x2, y2) on the Cartesian plane. The equation for the distance is:

distance equation

For example, the call of distance(1, 0, 4, 4) would return 5.0 and the call of distance(10, 2, 3, 5) would return 7.615773105863909.
