"What is array in Java"

What is array in Java:

A container object called an array carries a predetermined number of values of a single kind. When an array is constructed, its length is predetermined. Its length is fixed once it is created. Earlier, in the main method of the "Hello World!" application, you saw an example of an array.

A grouping of comparable types of data is called an array.

An array is a set of items, images, or numbers arranged in rows and columns.

For example, if we want to store the names of 10 people then we can create an array of the string type that can store 10 names.

Example:-

String[] array = new String[10];

                     

Here, the above array cannot store more than 10 names. The number of values in a Java array is always fixed.

Types?

• Two-Dimensional Arrays.
• Three-Dimensional Arrays.
• Multi-Dimensional Arrays.

A homogenous non-primitive data type called an array is used to store many elements with the same data type in a single variable. Java arrays support both non-primitive and primitive data types, such as Integer, Character, Float, etc (Object).

                             

What advantages does array offer?

The array data structure's benefits:

Multiple data of the same name and similar types are stored in arrays.

It enables access to elements at random.

There is neither a memory deficit nor an overflow because the array is fixed in size and stored in adjacent memory locations.

Any type of data with a fixed size should be stored.
