This class specifies a supported resolution in DPI (dots per inch). Resolution defines how many points with different color can be placed on one inch in horizontal or vertical direction of the target media. For example, a printer with 600 DPI can produce higher quality images the one with 300 DPI resolution.

Compares this instance with the specified object and indicates if they
are equal. In order to be equal, o must represent the same object
as this instance using a class-specific comparison. The general contract
is that this comparison should be reflexive, symmetric, and transitive.
Also, no object reference other than null is equal to null.
The default implementation returns true only if this ==
o. See Writing a correct
equals method
if you intend implementing your own equals method.
The general contract for the equals and hashCode() methods is that if equals returns true for
any two objects, then hashCode() must return the same value for
these objects. This means that subclasses of Object usually
override either both methods or neither of them.
| obj | the object to compare this instance with. |

true if the specified object is equal to this Object; false otherwise.Gets the horizontal resolution in DPI (dots per inch).
Gets the unique resolution id. It is unique amongst other resolutions supported by the printer.
This id is defined by the client that generated the resolution instance and should not be interpreted by other parties.
Gets the resolution human readable label.
Gets the vertical resolution in DPI (dots per inch).
Returns an integer hash code for this object. By contract, any two
objects for which equals(Object) returns true must return
the same hash code value. This means that subclasses of Object
usually override both methods or neither method.
Note that hash values must not change over time unless information used in equals comparisons also changes.

hashCode method
if you intend implementing your own hashCode method.
Returns a string containing a concise, human-readable description of this object. Subclasses are encouraged to override this method and provide an implementation that takes into account the object's type and data. The default implementation is equivalent to the following expression:
getClass().getName() + '@' + Integer.toHexString(hashCode())
