question: public boolean equals ( Object obj ) { if ( this == obj ) return true ; if ( obj instanceof EllipticCurve ) { EllipticCurve curve = ( EllipticCurve ) obj ; if ( ( field . equals ( curve . field ) ) && ( a . equals ( curve . a ) ) && ( b . equals ( curve . b ) ) ) { return true ; } } return false ; }
target:  Compares this elliptic curve for equality with the specified object.
