Difference between int[] array and int array[]

I was sure that this question is already asked and just wrote the title to find it, but to my surprise it wasn’t. I was working on one issue and this question raised. I tried this:

int[] x = new int[1];
int y[] = new int[1];
x=y;
y=x;

and compiler didn’t give me an error. So is there any difference between these two declarations?

Answer 1

There is no difference in semantics. Both syntaxes mean the same. Some extract from the JLS §10.2:

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, as in this example:

byte[] rowvector, colvector, matrix[];

This declaration is equivalent to:

byte rowvector[], colvector[], matrix[][];

However, as Voo states in the below comments, there can be some tricky confusion about these declarations when declaring several arrays in a single statement.
