Referencer mellem objekter i ArrayList ?

Jeg tror ikke, at du opretter de to objecter i hver deres arraylist. ArrayList er bare en specialiseret collection (holder på en samling af objekter - data bag). Så du skal nok oprette de to objekter (o1 og o2) og sætte deres ref. til hinanden (o1.setRef(o2) o2.setRef(o1)) også er det ligemeget om du tilføjer dem til en arrayList eller hvad du gør med dem, men de vil altid have denne reference til hinanden.

eller hvis du selv har programmeret disse objekter programmere plads til at de kan gemme en reference på andre objekter.. du laver bare en metode til formålet.

hej kalp
Kan du give et eksempel på den kode du snakker om

Hvis du har et objekt som fx denne


public class Test
{
public test
{
}
}

og du vil have den skal kunne have en reference til et andet objekt af samme type..

så kan du gøre sådan her

public class Test
{
Test ref;
public test
{
}
public void makeref(Test ref)
{
this.ref = ref;
}

}


hvis jeg altså har forstået det korrekt... og så kan du jo lave metoder til at fjerne den igen.. eller hente den.. men referencen er der!

hej kalp...kan du ikke også lige kigge på denne her:

Jeg skal nok sende flere point
