Passing Scanner Object as a Parameter in Java
Last Updated :

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
{
Scanner sc = new Scanner(System.in);
Sample ob = new Sample();
ob.examplemethod(sc);
}
}
|
Output:
What is your name?
