Question

package learn2;
import java.util.Scanner;

public class Main {

public static void main(String[] args) {

Scanner input = new Scanner (System.in);
System.out.println("Enter your name ");
String name = input.nextLine(); // I entered No. 2 , and still working. why there is no exception here !!!!!!
System.out.println("You are welcome ");

}

}

// Why the code is executed even if I put an int. I declared the variable name as a string.

Answer 1

2 is read in as a string. So there is no exception. Also, 2 is a valid string.
