class Connection
{   int index;
	static int count;	
	private Connection() 
	{
		count++;
		System.out.println("Object"+count+"  construct");
		setID(count);
	}
	void setID(int n)
	{
		index = n;
	}
	public static Connection[] makeConnection(int x)
	{  
		Connection[] ps1=new Connection[x];
		for(int i=0;i<x;i++)
		{
			 ps1[i] = new Connection();
			
		}
		 return ps1;
	}
	
}

public class ConnectionManager
{   
    
	public static void main(String[] args)
	{
		Connection[] ps2 = Connection.makeConnection(6);
		for(int j=0;j<6;j++)
		System.out.println("引用对象号"+ps2[j].index);
	}
}
