Class EqualUtils



  • public final class EqualUtilsextends Object
    Collected methods which allow easy implementation of equals. Rewritten from http://www.javapractices.com/topic/TopicAction.do?Id=17. Example use case in a class called Car:
    public boolean equals(Object aThat){  if ( this == aThat ) return true;  if ( !(aThat instanceof Car) ) return false;  Car that = (Car)aThat;  return    EqualsUtil.areEqual(this.name, that.name) &&    EqualsUtil.areEqual(this.numDoors, that.numDoors) &&    EqualsUtil.areEqual(this.gasMileage, that.gasMileage) &&    EqualsUtil.areEqual(this.color, that.color) &&    Arrays.equals(this.maintenanceChecks, that.maintenanceChecks); //array!} 
    Arrays are not handled by this class. This is because the Arrays.equals methods should be used for array fields.
