In this tutorial you will learn about the Java Program to print elements of an array and its application with practical example.
Java Program to print elements of an array
In this tutorial, we will learn to create a Java program that will Print Elements in an Array using Java programming.
Prerequisites
Before starting with this tutorial, we assume that you are the best aware of the following Java programming topics:
- Operators in Java Programming.
- Basic Input and Output function in Java Programming.
- Basic Java programming.
- For loop in Java programming.
- Arithmetic operations in Java Programming.
What is an array?
An array in a programming language is a collection of a similar set of entities. It means one variable can store multiple values in memory with different indices.
Algorithm:-
1 2 3 4 5 6 7 8 9 |
Step 1 :- Initialization of the program. Step 2 :- Taking the input size of the array. Step 3 :- Taking the elements of the array from the user for the program. Step 4 :- Using for loop to print the elements of the array to the user. Step 5 :- Ending the execution of the program. |
Printing the Elements in an Array.
In this program, First, we will first take the size of the array from the user. Then we will take the elements of the array from the user. After that, we will use a for loop to print the elements of the array.
With the help of this program, we can be print the elements of the array.
Program Code:-
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 |
import java.util.*; public class ArrayPrint { private static Scanner sc; public static void main(String[] args) { //Declaring the required variables for the program. int i, no; sc = new Scanner(System.in); //Taking the size of the array System.out.print(" Please Enter number of elements in an array : "); no = sc.nextInt(); int [] Array = new int[no]; //Taking the elements of the array from the user. System.out.print(" Please Enter " + no + " elements of an Array : "); for (i = 0; i < no; i++) { Array[i] = sc.nextInt(); } //Printing the elements of the array. System.out.println("\n **** Elements in this Array are **** "); for (i = 0; i < no; i++) { System.out.print(Array[i] + "\t"); } } } |
Output:-
In the above program, we have first initialized the required variable.
- no = it will hold the integer value.
- i = it will hold the integer value.
Taking the size of the array and the elements.
Printing output elements of the array.
