How To Take Array Input In Java

In this article we will show you the solution of how to take array input in java, we'll get how to take array input in Java. Therefore, before taking inputs, let's first define an array.

A collection or set of components that are kept together and assigned the same data type and variable name is known as an array.

In Java, all data collections are referred to as objects or collection frameworks. Now move to the concept of how to take array input in java.

Step By Step Guide On How To Take Array Input In Java :-

Among objects, an array is a type of object. The kind of collection structure includes array lists.

Delimiters :- Delimiters are particular symbols that are specifically created for a

The delimiters for a function or class body are curly brackets ().

Java doesn't have a straightforward method to accept input from arrays.

However, we can accept array input by utilising the Scanner class’s function.

We must inquire the user about the length of the array before we can bear input from it.

The user's input is then captured using a Java for loop, and the same for loop is also used to get the array's items.

Any primitive type can be used as input, and the appropriate primitive type method can be used to take input for array elements.

Every class name must begin with a capital letter, and the main should be the name of a programme or file.


  • Only a small amount of memory is required to create this array.
  • There is no memory loss


  • The identical response will always be displayed on the output screen for each compilation.
  • Not respected as a capable programmer.
  • Presented in a static manner.

We will develop a programme utilising the dynamic technique of programming to address the issues that have been brought up by the above method.

Here, we'll use the java.util package to implement dynamic programming.

In this context, dynamic programming refers to the concept of assigning values to a specified array while it is running.

import java.util.Scanner;
public class ArrayInputExample1
public static void main(String[] args)
int j;
Scanner sc=new Scanner(;
System.out.print("Enter the number of elements: ");
int[] array = new int[10];
System.out.println("Enter the array elements: ");
for(int i=0; i<j; i++)
System.out.println("Array elements are: ");
for (int i=0; i<j; i++)
  1. To implement dynamic programming, package is used in the first line of code.
  2. Next, we develop the ArrayInputExample1 public class.
  3. Next, we employ public static void main (String[] args).
  4. Next, the int keyword is used to save a variable.
  5. Next, we employ Java's Scanner class. It uses the util package to read input data from many sources.
  6. Next, the statement is printed.
  7. Our next step is to read the number of elements that the user wants in order to access them using the scanner class
  8. Following that, we create an array with a memory size of
  9. We print the message once more.
  10. The for loop is used next.
  11. Once more, for reading array elements from the user, we use the scanner class.
  12. We utilise the print statement once more.
  13. Next, we use a for loop to access the array elements.
  14. Then, with the aid of the system, we can see the system.out.println.

Conclusion :-

As a result, we have successfully learned how to use an array as input in Java.

Additionally, we learned about the idea of delimiters. We can also see the idea of a scanner class in java.

I hope this article on how to take array input in java helps you and the steps and method mentioned above are easy to follow and implement.
