class CMyint
{
private int n;
public CMyint(int i)
{
	System.out.println("CMyint("+ i+")");
	n=i;
}

public CMyint(CMyint other)
{
	System.out.println("CMyint(CMyint other)"+other.n);
	n=other.n;

}
public class Main{
    public static void main(String[] args) {
		CMyint obj=new CMyint(3);
		CMyint obj2=new CMyint(obj);
    }
}

输出：

CMyint(3) 
CMyint(CMyint other)3

public class Main{
     public static void main(String[] args) {
CMyint obj=new CMyint(3);
//CMyint obj2=new CMyint(obj);
     }
 }

输出：

CMyint(3)
