Playing with cubes II

Description:

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()
  {

  }
  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 = ){
    SetSide(Side);
  }

  public Int32 GetSide()
  {
    return this._side;
  }

  public void SetSide(Int32 Side)
  {
    this._side = Math.Abs(Side);
  }
}
