.length

[William Barnes]

I know I can say ".length" on an array. Where is this defined? Can I say anything else, like ".size" maybe?

[Ron Newman]

.length is a fundamental property of any array. It's "defined" in the Java Language Specification.
Since an array is an Object, you can also call methods such as equals(), hashCode(), getClass(), notify(), wait(), etc.

[James Chegwidden]

Yes, since arrays are objects .length is an instance variable.

Which is what I am asking. Is it in java.lang.*, java.io.*? Where is it?

Array is not a Java class in the sense that you will find it in the API. (There is an Array class but it is part of the reflecyion API).

Thanks - that is what I was looking for.
