It's because you are trying to compare an integer to a scanner. your "age" variable shouldn't be a scanner, but the scanners nextInt

No, not like that. firstly, I don't think you need 2 scanners. You could do it like this: Scanner sc = new Scanner(System.in); String name = sc.nextLine(); //Alternatively, if it's only one word, you can use the next() method int age = sc.nextInt();

But you can get different datatypes with one scanner

based off what Airree says, you’re just not quite using the Scanner class correctly, this is how you would go about it: import java.util.Scanner; public class Program { public static void main(String[] args) { Scanner input = new Scanner(System.in); String name; int age; String civilState; //get name System.out.println("Write your name:"); name = input.next(); //get age System.out.println("Write your age:"); age = input.nextInt(); //get civil state System.out.println("Write your civil state:"); civilState = input.next(); if(age > 17 && age<46) { System.out.println(name+"\n"+age+"\n"+civilState); } else { System.out.println("Your age is not accepted"); } } }
