> Below statement throws compiler error.
> var arr = \{1,2};
> : error: cannot infer type for local variable var k = \{ 1 , 2 }; ^
> (array initializer needs an explicit target-type)
>  
> Proposed fix would be
>  int[] arr = \{ 1, 2 };
> The fix will be provided for Numeric primitive type array or for array with homogeneous members.
> a)Homogeneous type 
> 1. var arr =  \{ new Object(), new Object()};
> fix: Object[] arr = \{ new Object(), new Object()};
> 2. var arr = \{"hello", "world"};
> fix: String[] arr = \{"hello", "world"};
>  
> b)Primitive Type Numeric array 
>  var arr = \{1,2.2};
> fix: double[] arr = \{1,2.2};
