Initializing array through constructor

[Ashutosh Limaye]

Hi all,
Now though we popularly know that we cannot initialize the array reference by passing the values in constructor,like:

public class TestArray
{
   private int arr[];
   public TestArray(int a[])
   {
      this.arr=a;
   }
   .
   .
   .
   public static void main(String args[])
   {
      TestArray t=new TestArray({10,20,30,40,,50}); // <====== HERE IS THE PROBLEM
    }
}

I was thinking what was the reason behind dis-allowing this method? Is there any alternate method? 'cause otherwise there is going to be
always an additional reference in main's stack frame pointing to the array object on heap... which is kind of not a good idea.
comments please.

regards

Hi,

TestArray t=new TestArray({10,20,30,40,50});

This is like The constructor TestArray (int, int, int, int, int) .

 TestArray t=new TestArray(new int[]{10,20,30,40,,50});//This works fine

Or make it a varags parameter

    public class TestArray  
    {  
       private int arr[];  
       public TestArray(int... a)  
       {  
          this.arr=a;  
       }  
       .  
       .  
       .  
       public static void main(String args[])  
       {  
          TestArray t=new TestArray(10,20,30,40,50); 
        }  
    }
