Assuming that the method returns a type consistent with what the array holds, you can assign a method's return value to an array like this...

myArray[x] = myMethod();

I'm not sure I understand what you mean by "the value = length of array," but if the array is declared to hold int values, you could certainly do this...

myArray[x] = myArray.length;

You can have an array:-You can pass the array as an argument to a method.
You can get the method to return an array.
You can pass a number and get a method to produce an array that size.
You can get the length attribute of any array, which is a common-or-garden int number, and pass it as an argument. You name it, you can do it.

You use [] when you are creating the array, or referring to a aprticular member.

If you are referring to a whole array, you miss out the [].

I’ve looked at a lot of different solutions, and in my humble opinion Aspose is the way to go. Here’s the link: http://aspose.com
