Class CollisionSystem

java.lang.Object

edu.princeton.cs.algs4.CollisionSystem

public class CollisionSystem
extends java.lang.Object

The CollisionSystem class represents a collection of particles moving in the unit box, according to the laws of elastic collision. This event-based simulation relies on a priority queue.

For additional documentation, see Section 6.1 of Algorithms, 4th Edition by Robert Sedgewick and Kevin Wayne.

Constructor Detail

CollisionSystem

public CollisionSystem(Particle[] particles)

Initializes a system with the specified collection of particles. The individual particles will be mutated during the simulation.

Parameters:

particles - the array of particles

Method Detail

simulate

public void simulate(double limit)

Simulates the system of particles for the specified amount of time.

Parameters:

limit - the amount of time

main

public static void main(java.lang.String[] args)

Unit tests the CollisionSystem data type. Reads in the particle collision system from a standard input (or generates N random particles if a command-line integer is specified); simulates the system.

Parameters:

args - the command-line arguments
