Instantiate a inner class object

[Waria Ahmed]

Hi there,

I'm teaching myself about inner classes and am just practicing some code to test what I've learnt. Unfortunately I have got stuck instantiating a object, the following is my code. Would be grateful if anyone could assist me:

  public class uni {
 
    public uni() {
    }
    public class Student{
String firstName;
String secondName;
    
    public Student(String firstName, String secondName){
    this.firstName = firstName;
    this.secondName = secondName;
    }
    public void getFullDetails(){
    System.out.println("first name : " + firstName + " second name: " + secondName);
    }
    
    }
    
    public static void main (String[] args){
    uni.Student Irfan = new Student("Irfan", "Nabi");
  Irfan.getFullDetails();
    }
    
}  

I get the error on the line where im trying to create a object. Thanks

Your Student inner class is not static. Therefore, as all other non-static members (fields, methods), you will need an instance of the enclosing class first:

new uni().new Student("Irfan", "Nabi");

Either that, or make the class static.
