Java Scanner help

So i was reading the posts on my latest thread (is Eclipse nessesery?) and i downloaded eclipse and have been working on Java for about 2 months now but i ran into a problem, so i want player to input a integer but the Scanner isn't working. Here's the code:

Code:

---

import java.util.Scanner;

public class Character_Creation {
        public static void main(String[] args) {
                Scanner name = new Scanner(System.in);
                Scanner a = new Scanner(System.in);
            int age = a.hasNextInt();
               
                if (age < 18) {
                        System.out.println("Too young!");
                }else{
                        System.out.println("Welcome " + name.nextLine());
                }       
        }

}

Code:

---

import java.util.Scanner;


public class Character_Creation {

        public static void main(String[] args) {
                Scanner scan = new Scanner(System.in);
               
                String name;
               
                System.out.print("Enter your name: ");
                name = scan.next();
               
                System.out.print("Test this age: ");
                int age;
                try{
                        age = scan.nextInt();
                        if (age < 18) {
                                System.out.println("Too young!");
                        }else{
                                System.out.println("Welcome "+name.toString());
                        }
                }catch(Exception e){
                        System.out.println("User failed to enter a number.");
                }
               
        }

}
