What is length field?
Rating:
All arrays in Java have a public final field known as length. This field is used to find the number of elements that the array holds. Once an array is created, its size can be obtained by using the length field qualified by the array name along with a dot operator. For example, the given statement finds the size of the array named MyArray.
The length field of an array always has a non-negative value. If the length of an array is zero, it is called an empty array.
