Setters and Getters Java

Question

If age is under 0,you have to print a messages "Invalid option", Age : 0 and name else print just the name and age. I tried by my own, but it works only for age<0.So if someone know to solve and wants to help, I will be very thankful.
import java.util.Scanner;
class Main {
public static void main(String[] args) {
Scanner read = new Scanner(System.in);
String name = read.nextLine();
int age = read.nextInt();
Student student = new Student();
student.name = name;
Student sa = new Student();
sa.setAge (age);
System.out.println("Name: " + student.name);
System.out.println("Age: " + student.getAge());
}
}
class Student {
public String name;
private int age;
public int getAge() {
return age;
}
public void setAge(int age) {
if (age<0){
System.out.println("Invalid age");
this.age = 0;
}else{
this.age = age;
}
}
}
