如何在两个activity中传类对象

public class MyClass implements Serializable{
private int number;
private int max;
private int min;
private ArrayList<String> url;

public void SetNumber(int number)
{
  this.number = number;
}

public void SetMax(int max)
{
  this.max = max;
}

public void SetMin(int min)
{
  this.min = min;
}

public void SetUrl(ArrayList<String> url)
{
  this.url = url;
}

public int GetNumber()
{
  return number;
}

public int GetMax()
{
  return max;  
}

public int GetMin()
{
  return min;
}

public ArrayList GetUrl()
{
  return url;
}

}


然后创建2个Activity,来传递数据。
发送部分代码：
Intent intent = new Intent();
intent.setClass(TestActivity.this, OtherActivity.class);
intent.putExtra("myclass", myclass); 
startActivity(intent);


接收部分代码：
Intent intent = getIntent();        
myclass = (MyClass)intent.getSerializableExtra("myclass");
