Passing Scanner Object as a Parameter in Java
There are different ways to input data from the user using Scanner Class. Every time when we need input from the user a Scanner object is declared. Sometimes there is a possibility of getting a restriction on the number of objects that can be created. So we may not get a chance to create another object in order to input data from the user. In such a situation, we can pass a Scanner object that is already created as a parameter to the method where you need to input the data. The below code helps you to get a clear idea about it!
Example Code:
Java
import java.util.*; public class Sample { public void examplemethod(Scanner sc) { System.out.println("What is your name? "); String name = sc.next(); System.out.println("Your name is " + name + "!"); } public static void main(String args[]) throws IOException { // Instantiating the Scanner class Scanner sc = new Scanner(System.in); Sample ob = new Sample(); // Calling the method and // Passing the Scanner Object ob.examplemethod(sc); } } // Contributed by PL VISHNUPPRIYAN |
Output:
What is your name? VISHNUPPRIYAN Your name is VISHNUPPRIYAN!
