public boolean equals(java.lang.Object obj)
Description copied from class:AbstractQuantity
Compares this quantity against the specified object for strict equality (same unit and same amount).Similarly to the
BigDecimal.equals(java.lang.Object)
method which consider 2.0 and 2.00 as different objects because of different internal scales, quantities such asQuantities.getQuantity(3.0, KILOGRAM)
Quantities.getQuantity(3, KILOGRAM)
andQuantities.getQuantity("3 kg")
might not be considered equals because of possible differences in their implementations.To compare quantities stated using different units or using different amount implementations the
compareTo
orequals(Quantity, epsilon, epsilonUnit)
methods should be used.- Overrides:
equals
in classAbstractQuantity<Q extends javax.measure.Quantity<Q>>
- Parameters:
obj
- the object to compare with.- Returns:
this.getUnit.equals(obj.getUnit()) && this.getValue().equals(obj.getValue())
