Question

import java.util.Scanner ;
public class Program

{
public static void main(String[] args) {
System.out.println("Write your name:");
Scanner name = new Scanner(System.in);
// System.out.println(name.nextLine());
System.out.println("Write your age:");
Scanner age = new Scanner(System.in);
// System.out.println(age.nextInt());
System.out.println("Write your civil_state");
Scanner civil_state = new Scanner(System.in);
// System.out.println(civil_state.nextLine());
if(age > 17 && age<46){
System.out.println(name.nextLine());
System.out.println(age.nextInt());
System.out.println(civil_state.nextLine());
}
else {
System.out.println("Your age is not accepted");
}
}
}

Answer 1

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

Answer 2

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();

Answer 3

But you can get different datatypes with one scanner

Answer 4

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");
}
}
}

Answer 5

how i fix that? any sugesstion?
like that for example:
Scanner age = newScanner.nextInt(System.in); and thanks Airre

Answer 6

ohhhhhh guauuu, it is not necessary because i have three scanner one for type of data.
