How to call an object from another class?

[narty]

Hello

In my java homework i have to have a field, from a class called Cd point to an object from another class (Person). Now i have tried mighty hard but i just cannot make the final connection, i understand that the class Cd will have a field of type Person which would mean it holds information about an object from that class. i think?

So now my lecturer described it to me with a telephone number example, i could go round the class and get everyones number or i could just get them to write it on a piece of paper and request the paper, which i gathered resembles an object i.e it has the information stored in its fields

Now my issue is how do i call that object from a method in another class i think im going down the right tracks but i seem to be getting more and more confused please can somebody steer me in the right direction?

hello, i don't know if i got your reguirements by 100% but i have implemented an example:

class Person {
	String phoneNr;
	
	public void setPhoneNr(String phoneNr) {
		this.phoneNr = phoneNr;
	}
	
	public String getPhoneNr() {
		return this.phoneNr;
	}
}

public class Cd {
	
	Person person;
	
	public void setPerson(Person p) {
		this.person = p;
	}
	
	public Person getPerson() {
		return this.person;
	}

	/**
	 * @param args
	 */
	public static void main(String[] args) {
		Person p = new Person();
		p.setPhoneNr("1234");
		
		Cd cd = new Cd();
		cd.setPerson(p);
		// get phonenumber from cd.person
		System.out.println("phone number = " + cd.getPerson().getPhoneNr());
	}
}

what do you think?
