LinkedList Problems (trimming or something)

Hey all, i am pleased to say that I think i have a better understanding of how java works now but i have run into a problem when using linked list. I want to make a list full of objects and when i make a call directly to the list eg list.add(object) everything is fine and i can add as many objects as i want, however when i create a method to do this (for encapsulation purposes) it only lets me add three objects to the list then stops adding more even if i call the method again.:confused:

If anyone knows whats happening i would really appreciate some advice thanks

Not without seeing your code. If it is too long create a SSCCE (google it).

No one would know whats happening unless you show them what have you done actually... We can't guess it, right?

We can actually. I guess it is because OP is wearing green socks.

Code:

public class runThis {
        Cat cat1 = new Cat();
        Cat cat2 = new Cat();
        Dog dog1  = new Dog();
        Dog dog1  = new Dog();
        public static void main(String[] args){
                AnimalList animalList = new AnimalList();
                animalList.List.add(Cat1);
                animalList.List.add(Cat2);
                animalList.List.add(Dog1);
                animalList.List.add(Dog2);
                System.out.println("Start");
                System.out.println(animalList.List.size());
                for(Animal creature:animalList.List){
                        System.out.println(creature);
                } 
   
                AnimalList animalList = new AnimalList();
                animalList.addAnimal(Cat1);
                animalList.addAnimal(Cat2);
                animalList.addAnimal(Dog1);
                animalList.addAnimal(Dog2);
                System.out.println("Start");
                System.out.println(animalList.List.size());
                for(Animal creature:animalList.List){
                        System.out.println(creature);
                } 
        }
}

Code:

---

public class animalList{
                public ArrayList<Animal> List = new ArrayList<Animal>();
               
                public void addAnimal(Animal theAnimal){
                        List.add(theAnimal);
                }
}

So when i insert the animals in the first way, i can insert as many as i want, but when i insert them using my addAnimal method it only lets me add 3. Any ideas

oh and green socks? lol

I asked for a SSCCE which stands for Short Self-Contained Compilable Example. Your code is far from compilable.

What makes you think that you can only add 3 objects to the list? If you correct the multitude of errors, the code will indeed work for 4 or more objects.

Exactly as Junky said... The code will will work if OP can understand that Java is case sensitive. Which means that Cat1 is NOT the same as cat1.

Plus, duplicate variables [like dog1] are not allowed unless you have customized your compiler to work as per your own wish.
