Is there any difference between "Object[] x" and "Object x[]"?

Question

I was updating a legacy code base in Java and I found a line like this: ``` Object arg[] = { new Integer(20), new Integer(22) }; ``` That line catched my attention because I am used to this kind of code: ``` Object[] arg = { new Integer(20), new Integer(22) }; ``` The content of the array isn't important here. I'm curious about the brackets next to the variable name versus the brackets next to the class name. I tried in Eclipse (with Java 5) and both lines are valid for the compiler. Is there any difference between those declarations?

Accepted Answer

Both are legal and both work. But placing [] before the array's name is recommended.

From Javadocs:

You can also place the square brackets after the array's name:

```
float anArrayOfFloats[]; // this form is discouraged
```

However, convention discourages this form; the brackets identify the array type and should appear with the type designation.
