public XYZ()
```
    Creates a new instance of XYZ
  - XYZ
```
public XYZ(double x,
           double y,
           double z)
```
    Create a new XYZ coordinate
    
    Parameters:
    
    x - The X component
    
    y - The Y component
    
    z - Th Z component
- Method Detail
  - x
```
public double x()
```
    Get the X component
    
    Returns:
    
    The X component
  - y
```
public double y()
```
    Get the Y component
    
    Returns:
    
    The Y component
  - z
```
public double z()
```
    Get the Z component
    
    Returns:
    
    The Z component
  - hashCode
```
public int hashCode()
```
    Provide a hashcode for this XYZ based on the values contained. This is necessary to meet the contract for the Object.hashcode() method which requires that if object1.equals(object2) their hashcodes must also be equal.
    
    Overrides:
    
    hashCode in class java.lang.Object
    
    Returns:
    
    hashcode
  - equals
```
public boolean equals(java.lang.Object obj)
```
    Compare this XYZ with another Object
    
    Overrides:
    
    equals in class java.lang.Object
    
    Parameters:
    
    obj - - the Objecty to compare to.
    
    Returns:
    
    true if obj is another XYZ containing the same values. They are not necessarily the same object.
