Hey Codewarrior!
You already implemented a Cube class, but now we need your help again! I'm talking about constructors. We don't have one. Let's code two: One taking an integer and one handling no given arguments!
Also we got a problem with negative values. Correct the code so negative values will be switched to positive ones!
The constructor taking no arguments should assign 0 to Cube's Side property.

using System; public class Cube { private int Side; //This cube needs your help. //Define a constructor which takes one integer and assignes its value to 'Side' public Cube() {} public Cube(int side) { this.Side = Math.Abs(side); } public int GetSide() { return this.Side; } public void SetSide(int s) { this.Side = Math.Abs(s); } }
可以使用this来处理构造函数,无参构造函数,字段的默认值,可以通过调用有参函数来处理
赋值的时候,可以调用类本身的函数
public class Cube { private int Side; //This cube needs your help. //Define a constructor which takes one integer and assignes its value to 'Side' public Cube(int s) { SetSide(s); } public Cube() : this(0) { } public int GetSide() { return Side; } public void SetSide(int s) { Side = System.Math.Abs(s); } }
可以使用函数的缺省参数
using System; public class Cube { private Int32 _side; public Cube(Int32 Side = 0){ SetSide(Side); } public Int32 GetSide() { return this._side; } public void SetSide(Int32 Side) { this._side = Math.Abs(Side); } }
