How to declare a variable without entering the value during the coding? About Java.

Question

I want to enter value at the output window

Answer 1

Are talking about html, Javascript, c#, python, c++, java or India language?

Answer 2

As far as I know, there is no way to declare a variable without assigning a value at the same time in Hindi or English, which are the two most used languages in India.

Answer 3

If you are talking about declaring a variable but use user input to assign it a value you can use a Scanner to ask for user to input a value

Example:
import java.util.Scanner;
class Example {
public static void main (String[] args) {
Scanner scan = new Scanner (System.in);
System.out.println("Please enter a value: ");
int userInput = scan.nextInt();
scan.close ();
}
}
