Create an Array in Java
Overview
In this tutorial, let’s learn how to create an array in Java programming language. An array is a collection of elements. An array in Java is dynamic. We specify the size of the array at runtime.
All the elements of the array are of the same data type. The array elements are commonly referred to using a single name and individual elements are accessed using the index.
Declare an Array
The syntax to declare an integer array is as follows:
int numbers[]; //declare an integer array
int [] marks; // another syntax to declare an array
Create an array
Create an array of 10 elements
int numbers = new int[10];
Alternatively, you can declare and allocate memory in two steps.
//Declare an array
int numbers[];
//Create an array
numbers =new int[10];
We can also provide a variable in the array size declaration.
/* Create an array where the size of the array is determined by the value of variable num */
int arr[] =new int[num];
