How to Declare and Initialize One Dimensional Array in Java

 

One-dimensional arrays in Java are arrays that contain only one dimension. In other words, they can store elements but cannot be used to store other arrays.

To declare a one-dimensional array in Java, you need to specify the type of the elements and the number of elements in the array. Here's the general syntax for declaring a one-dimensional array:

package array;

import java.util.*;

public class OneD {

    public static void main(String[] args) {

        Scanner sc = new Scanner(System.in);

        System.out.println("Enter the digit number:");

        int n = sc.nextInt();

        int num[] = new int[n];

        System.out.println("Enter numbers :");

        for (int i = 0; i < n; i++) {

            num[i] = sc.nextInt();

        }

        System.out.println("You entered :");

        for (int i = 0; i < n; i++) {

            System.out.println(num[i]);

        }

        sc.close();

    }

}
