Array of objects declaration

Question

I am a bit confused with the 2 lines below.

MyClass myobj[];
myobj = new MyClass[numberVariable];

i would expect in line 1 something like:

MyClass[] myobj;

But the code works and there is not error.

What is the explanation?

Different ways of doing the same thing. – Tirath Oct 04 '14 at 15:33 — Tirath, Oct 04 '14 at 15:33

As the JLS states

The [] may appear as part of the type at the beginning of the declaration, or as part of the declarator for a particular variable, or both.

So even this is possible

float[][] f[][], g[][][], h[];

which is equivalent to

float[][][][] f;
float[][][][][] g;
float[][][] h;

and this is more readable, isn't it?

It gets worse than that. `public static int[]foo()[] { return new int[10][10];}` is valid too... – Jon Skeet Oct 04 '14 at 15:49

Both are valid syntax in Java, though MyClass[] myobj makes more sense to me, since you are declaring an array of type MyClass.
