How do you define an array?

An array is a collection of elements of the same type placed in contiguous memory locations that can be individually referenced by using an index to a unique identifier. Five values of type int can be declared as an array without having to declare five different variables (each with its own identifier).

What is array in Java and types?

Normally, an array is a collection of similar type of elements which has contiguous memory location. Java array is an object which contains elements of a similar data type. Additionally, The elements of an array are stored in a contiguous memory location. It is a data structure where we store similar elements.

What is an array and its types in Java?

There are two types of arrays in Java they are − Single dimensional array − A single dimensional array of Java is a normal array where, the array contains sequential elements (of same type) − int[] myArray = {10, 20, 30, 40}
