我得到的输出是: FRACTIONS@3d4eac69。有什么想法吗?public class FRACTIONS { public FRACTIONS (){ denom=1;numer;public int getDenominator (){}
public FRACTIONS add(FRACTIONS other){int d = denom * other.
a, a / b) ; // This will result in an error if b == 0CREATE TABLE Fractions( ,Denominator floatINSERT INTO FractionsVALUES (1, 2)
INSERT INTO Fractions
