我有一个程序可以将动物添加到Zoo数组中。动物分为不同类型,如飞行,陆地和水生。
我有一个子模块,它正在向数组添加一个飞行动物,但我得到了这个错误。
没有为Flying(int,double,string)找到合适的构造函数
这是创建数组的主要Zoo文件,负责将动物添加到数组中。

答案 0 :(得分:1)
构造函数的参数需要采用相同的顺序
因此您已将其定义为
public Flying(String inSpecies, double inMass, int inNumWings)
因此需要将其称为
Flying temp = new Flying(species, mass, numWings);
答案 1 :(得分:0)
构造函数中的参数顺序错误。
错误消息明确指出“ Flying(int,double,string)cons not found ”
这意味着您尚未定义接受“int,double,string”作为参数
的构造函数
