question: @ Override public boolean equals ( Object obj ) { if ( this == obj ) return true ; if ( obj == null ) return false ; if ( ! ( obj instanceof NdefRecord ) ) return false ; NdefRecord other = ( NdefRecord ) obj ; if ( ! Arrays . equals ( mId , other . getId ( ) ) ) return false ; if ( ! Arrays . equals ( mPayload , other . getPayload ( ) ) ) return false ; if ( mTnf != other . getTnf ( ) ) return false ; return Arrays . equals ( mType , other . getType ( ) ) ; }
target:  Returns true if the specified NDEF Record contains identical tnf, type, id and payload fields.
