利用方法重载编程

Question

java编写 计算球体体积，圆柱体体积，立方体体积 用方法重载编程，我不用重载的会，这重载的就不会了 还是就是形参要用几个

Answer 1

public interface Graph
{
public double volume();
}

//圆柱
public class Cylinder implements Graph
{
private double radius;

public Cylinder(double radius) {
    this.radius = radius;
}

@Override
public double volume()
{   
    //计算体积公式
    return 0;
}

}

//长方
public class Cuboid implements Graph
{
private double width;
private double height;
private double length;

public Cuboid(double width, double height, double length)
{
    this.width = width;
    this.height = height;
    this.length = length;
}

@Override
public double volume()
{
    // 公式
    return 0;
}

}

//工具
public class ComputeUtil
{
public static double computeVolume(Graph graph) {
return graph.volume();
}
}

Answer 2

关于重载，可以参照下面的代码：

[code="java"]public class Volumn{

//球体体积
public float computeVolumn(float radius){

}

//圆柱体体积
public float computeVolumn(float radius, float height){

}

//长方体体积(包括立方体)
public float computeVolumn(float length, float width, float height){

}
