```
public class ProjCoordinate
extends java.lang.Object
```
Stores a the coordinates for a position defined relative to some CoordinateReferenceSystem. The coordinate is defined via X, Y, and optional Z ordinates. Provides utility methods for comparing the ordinates of two positions and for creating positions from Strings/storing positions as strings.
The primary use of this class is to represent coordinate values which are to be transformed by a CoordinateTransform.

    The X ordinate for this point.
    Note: This member variable can be accessed directly. In the future this direct access should be replaced with getter and setter methods. This will require refactoring of the Proj4J code base.

  - z
```
public double z
```
    The Z ordinate for this point. If this variable has the value Double.NaN then this coordinate does not have a Z value.

- Constructor Detail
  - ProjCoordinate
```
public ProjCoordinate()
```
    Creates a ProjCoordinate with default ordinate values.
  - ProjCoordinate
```
public ProjCoordinate(double argX,
                      double argY,
                      double argZ)
```
    Creates a ProjCoordinate using the provided double parameters. The first double parameter is the x ordinate (or easting), the second double parameter is the y ordinate (or northing), and the third double parameter is the z ordinate (elevation or height). Valid values should be passed for all three (3) double parameters. If you want to create a horizontal-only point without a valid Z value, use the constructor defined in this class that only accepts two (2) double parameters.

  - ProjCoordinate
```
public ProjCoordinate(double argX,
                      double argY)
```
    Creates a ProjCoordinate using the provided double parameters. The first double parameter is the x ordinate (or easting), the second double parameter is the y ordinate (or northing). This constructor is used to create a "2D" point, so the Z ordinate is automatically set to Double.NaN.
  - ProjCoordinate
```
public ProjCoordinate(java.lang.String argToParse)
```
    Create a ProjCoordinate by parsing a String in the same format as returned by the toString method defined by this class.
    
    Parameters:
    
    argToParse - the string to parse
- Method Detail
  - setValue
```
public void setValue(ProjCoordinate p)
```
    Sets the value of this coordinate to be equal to the given coordinate's ordinates.
    
    Parameters:
    
    p - the coordinate to copy
  - setValue
```
public void setValue(double x,
                     double y)
```
    Sets the value of this coordinate to be equal to the given ordinates. The Z ordinate is set to NaN.
    
    Parameters:
    
    x - the x ordinate
    
    y - the y ordinate

    Sets the value of this coordinate to be equal to the given ordinates.
    
    Parameters:
    
    x - the x ordinate

```
public boolean areXOrdinatesEqual(ProjCoordinate argToCompare,
                                  double argTolerance)
```
    Returns a boolean indicating if the X ordinate value of the ProjCoordinate provided as an ordinate is equal to the X ordinate value of this ProjCoordinate. Because we are working with floating point numbers the ordinates are considered equal if the difference between them is less than the specified tolerance.
  - areYOrdinatesEqual
```
public boolean areYOrdinatesEqual(ProjCoordinate argToCompare,
                                  double argTolerance)
```
    Returns a boolean indicating if the Y ordinate value of the ProjCoordinate provided as an ordinate is equal to the Y ordinate value of this ProjCoordinate. Because we are working with floating point numbers the ordinates are considered equal if the difference between them is less than the specified tolerance.
  - areZOrdinatesEqual
```
public boolean areZOrdinatesEqual(ProjCoordinate argToCompare,
                                  double argTolerance)
```
    Returns a boolean indicating if the Z ordinate value of the ProjCoordinate provided as an ordinate is equal to the Z ordinate value of this ProjCoordinate. Because we are working with floating point numbers the ordinates are considered equal if the difference between them is less than the specified tolerance. If both Z ordinate values are Double.NaN this method will return true. If one Z ordinate value is a valid double value and one is Double.Nan, this method will return false.
  - equals
```
public boolean equals(java.lang.Object other)
```
    Overrides:
    
    equals in class java.lang.Object
  - hashCode
```
public int hashCode()

    Gets a hashcode for this coordinate.
    
    Overrides:
    
    hashCode in class java.lang.Object
    
    Returns:
    
    a hashcode for this coordinate
  - toString
```
public java.lang.String toString()
```
    Returns a string representing the ProjPoint in the format: ProjCoordinate[X Y Z].
    Example:
    ProjCoordinate[6241.11 5218.25 12.3]
    Overrides:
    
    toString in class java.lang.Object
  - toShortString
```
public java.lang.String toShortString()
```
    Returns a string representing the ProjPoint in the format: [X Y] or [X, Y, Z]. Z is not displayed if it is NaN.
    Example:
    [6241.11, 5218.25, 12.3]

```
public boolean hasValidXandYOrdinates()

    Indicates if this ProjCoordinate has valid X ordinate and Y ordinate values. Values are considered invalid if they are Double.NaN or positive/negative infinity.
