Question

Each array in Java has a public field named ________ that contains the number of elements in the array. A. size B. capacity C. length D. limit

Answer 1

C. length

the others are not fields

Answer 2

Answer:

(c) length

Explanation:

In Java, an array is a collection of data of the same type. Arrays have fixed length. As a matter of fact, arrays have a public field called length that contains the number of elements in the array.

For example, given the following array in Java;

int [ ] myarray = {3,2,3,3,3,4,4,3,4,3};

The array myarray contains 10 elements and can be accessed using the public field called length.

Therefore the following will return the number of elements (which is 10) in the array myarray;

myarray.length

The other options (size, limit and capacity) are not fields of an array object.
