Answer 1

you have 2 duplicate variables
i,e
int age
and Scanner age
Then you misused the new keyword which is used to create a new instance of an object

here is the correction ,ask if you do not understand it
import java.util.Scanner;
public class Program {
public static void main(String[] args) {
int a;

System.out.println("Please enter your age");
Scanner age=new Scanner(System.in);

a= age.nextInt();
if(a > 0) {
if(a > 16) {
System.out.println("Welcome!");
} else {
System.out.println("Too Young");
}
} else {
System.out.println("Error");
}
}
}
