Difference between String[] and Array<String>

Question

I'm new to Java and I can't figure out what the difference between String[] and Array<String> is. And how do I actually count how many entries a String[] Array has? Thanks!

What's Array<String>? I can't find any Array<T> class in the JDK reference, and my JDK's javac won't let me compile an Array<String> foo; declaration. There's ArrayList<T>, but that's something else entirely. — T.J. Crowder

Probably IDE autocompletion gave him the java.lang.reflect.Array class. — bezmax

String[] - is an array

Array - is a part of reflection API which you shouldn't bother about until you get more experience in java.

String[] a = new String[length]; - is a proper instantiation of array

a.length - returns length of the array

Main difference: String[] is not resizable.

Length of String[]: use .length property.
