You need to put everything inside try block if you want to catch them.
Copy this code on Sololearn playground and see the effect
import java.util.Scanner;
public class Program
{
public static void main(String[] args) {
Scanner sc = new Scanner (System.in);
try {
int n = sc.nextInt();
System.out.println("Hello " + n);
} catch (Exception e) {
System.out.println("Enter only numeric value => " + e);
}
}
}

Answer 5

You can use a while true loop and break after getting a correct input.
Note that you have to use scanner.next() in catch or the program will use your last input instead of asking you for a new one.
