What does an array hold?

An array is an average data structure that holds similar values of same data type. Arrays can hold references as well as primitives. For storing and accessing a sequence of objects, Array is the most efficient data structure

Here is the list of most important array features you must know.
• copying and cloning
• insertion and deletion
• searching and sorting

As it is generally known, the Java language has only two data types which is the Primitives data type and References data type. An array is not a primitive data type because it has only one field called length. Hence, an array is a reference type.
