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?
Arrays in Java are not resizable. Once an array is instantiated, its length cannot change. That’s why the
lengthattribute (myArray.length) can always be trusted to contain the array’s length.
