java simple output of name and age [duplicate]

Question

Im kind of new to java and im struggling very hard at this one. I just want to make a syso with the age and name of Stefan

    public class Person {

    public int alter;
    public String placeofbirth;

    public Person(int alter, String placeofbirth) {
    this.alter = alter;
    this.placeofbirth = placeofbirth;
    }

    Person stefan = new Person(19, "Berlin");

    public String toString() {
    return "test" + stefan;
    }

    public static void main(String[] args) {

    System.out.println(stefan);
    }

    }

What am i doing wrong?

Would be very grateful to get help

You have to add the @override annotation to toString method to overwrite it. System.out.println will call automatically the toString method. — ChW

@ChW The @Override tag only produces an error when the method doesn't actually overrides a method, it's not necessary but very useful. — Edwardth

The toString() of Person would create an awful StackOverflowError because it's a recursive method. Change it to public String toString(){ return "test "+alter+" "+placeofbirth;}. Also the Person stefan isn't in the scope of the main method. — Edwardth
