Single Dimensional Array In Java

Welcome back, bloggers! In this post you will learn about single dimensional arrays in Java.
First of all, what is an array? An array is a fixed sized sequenced collection of elements of a same data type.
Array in Java is index-based. The very first element is stored at 0^th position.

Advantages of array in Java:

1. Memory does not get wasted.
2. We can get any data located at any fixed index value.

Single Dimensional Array in Java:

A single dimensional array contains only one row and no number of columns.

Syntax:     datatype name[];

Initialization of a single dimensional array:     array[] = new int[5];


Now, let's see an example of a single dimensional array:

class JavaArray {

     public static void main(String[] args) {

int array[]; //declaration
     array = new int[5];  //instantiation

a[0] = 1;  //initialization
a[1] = 2;
a[2] = 3;
a[3] = 4;
a[4] = 5;

//printing the array:
for(int i=0; i<=array.length; i++)
System.out.println(array[i]);
                                  }
                             }






A single dimensional array can also be made by the following way:

Syntax:     int array[] = {10,20,30,40,50};

Example:

class JavaArray {
public static void main(String[] args) {
int array[] = {10,20,30,40,50}; //initialization, instantiation and declaration

//printing the array:
for(int i = 0; i<=array.length; i++)
System.out.println(array[i]);
                      }
               }




Thank you for coming to my blog. Now you have learnt how to declare, instantiate, initialize and print a single dimensional array!
