  - integrate
```
public double integrate(long n)
```
    Run the Monte-Carlo integration.
    
    Parameters:
    
    n - Number of random points to generate.
    
    Returns:
    
    the integral.
  - isInside
```
protected abstract boolean isInside(double... point)
```
    Indicates whether the given points is inside the region whose integral is computed.
    
    Parameters:
    
    point - Point whose coordinates are random numbers uniformly distributed in the unit interval.
    
    Returns:
    
    true if the point is inside.
