question: @ Override public boolean equals ( Object otherRules ) { if ( this == otherRules ) { return true ; } if ( otherRules instanceof ZoneRules ) { ZoneRules other = ( ZoneRules ) otherRules ; return Arrays . equals ( standardTransitions , other . standardTransitions ) && Arrays . equals ( standardOffsets , other . standardOffsets ) && Arrays . equals ( savingsInstantTransitions , other . savingsInstantTransitions ) && Arrays . equals ( wallOffsets , other . wallOffsets ) && Arrays . equals ( lastRules , other . lastRules ) ; } return false ; }
target:  Checks if this set of rules equals another. <p> Two rule sets are equal if they will always result in the same output for any given input instant or local date-time. Rules from two different groups may return false even if they are in fact the same. <p> This definition should result in implementations comparing their entire state.
