- edu.princeton.cs.algs4.CollisionSystem

```
public class CollisionSystem
extends 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.

```
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(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
