    Question 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.");
    		}
    		
    	}
    
    }
