Java Arrays - length

How do you determine the length of an array that is not an String array or an integer array? It won't let me use .length(), but only .length?

Why and is there another way of determining this?

Answer 1

You can use getLength method from java.lang.reflect.Array, which uses reflection (so it'll be slow):

Object[] anArray = new Object[2];
int length = Array.getLength(anArray);
