What is an array in Java?

We will learn to declare, initialize, and access array elements with the help of examples. An array is a collection of similar types of data . For example, if we want to store the names of 100 people then we can create an array of the string type that can store 100 names. String[] array = new String[100];

Arrays are used to store multiple values in a single variable , instead of declaring separate variables for each value.

An array is a container object that holds a fixed number of values of a single type . The length of an array is established when the array is created. After creation, its length is fixed. You have seen an example of arrays already, in the main method of the “Hello World!” application.
