程序报错找不到合适的构造器请问是什么原因？怎么解决？

Sphere(double x,double y,double z){
        xCenter=x;
        yCenter=y;
        zCenter=z;
        radius=1.0;
        ++count; // Update object count
    }

Sphere类只有三个参数的构造方法，你new的时候写了四个参数，要么删掉最后一个参数，要么改

Sphere(double x,double y,double z,double radius){
        xCenter=x;
        yCenter=y;
        zCenter=z;
        radius=radius;
        ++count; // Update object count
    }

按你的业务需求来

你没有定义四个参数的构造方法，没找到，要么删掉参数， 要么多定义一个构造方法
