    • equals

      public boolean equals(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(Object) method which consider 2.0 and 2.00 as different objects because of different internal scales, quantities such as Quantities.getQuantity(3.0, KILOGRAM) Quantities.getQuantity(3, KILOGRAM) and Quantities.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 or

      invalid reference 
      equals(Quantity, epsilon, epsilonUnit)
      methods should be used.

      Overrides:
      equals in class AbstractQuantity<Q extends javax.measure.Quantity<Q>>
      Parameters:
      obj - the object to compare with.
      Returns:
      this.getUnit.equals(obj.getUnit()) invalid input: '&'invalid input: '&' this.getValue().equals(obj.getValue())
