getDistance

public double getDistance(double x,
                          double y,
                          double z)

isInRange

public boolean isInRange(Point p,
                         double range)

isInRange

public boolean isInRange(double x,
                         double y,
                         double z,
                         double range)

copy
```
public Point copy(Point p)
```

plus
```
public Point plus(double val)
```

minus
```
public Point minus(double val)
```

isEqual
```
public boolean isEqual(Point p)
```
Utility method, confirms that coordinates of this point match the coordinates of the other point. Method equals() can't be used for that purpose as it includes object id - requirement for persistence.

Parameters:

p - Point to compare

Returns:

true if all coordinates are equal
