Strange array declaration in Java

Question

Project[[ | ]] array = new Project[[1 | 1]];

I am not getting which kind of array declaration is this? Also I don't know if it is correct or not. I tried it in Netbeans but it is not allowed. But in this example http://wiki.netbeans.org/OpenProjectsProgramaticallyInNetBeansIDE I found such example.

Give me some idea if it is correct.

It's not correct syntax. Seems to be a typo in the example code. — Kayaman

Doesn't seem to be correct syntax, even with the latest Java 8 conventions. I think it's just a typo, as Kayaman says. See here for documentation. — Mena

Project[] array = new Project[1]; is what they meant in that example. — zapl

According to javac from JDK7, it's invalid syntax (error: illegal start of expression pointing at the first [[). I assume it must be an error generating that page or some such.

This is invalid syntax. See the Java Language Specification for the correct syntax for declaring an array. Specification.

The specification specifically states:

An array initializer is written as a comma-separated list of expressions, enclosed by braces { and }.

There is no mention of adding pipes or nesting brackets.
