Sort a LinkedList of integers without method sort?

I want to know a simple method for sorting a LinkedList! I'm breaking my head and rolling the internet, but I only find methods that already perform the work I WOULD perform manually.

   public class OrdenacaoTeste {

    public static void ordenaLista(LinkedList<Integer> lista) {

    }

    public static void main(String[] args) {
        LinkedList<Integer> lista = new LinkedList<Integer>();

        lista.add(1);
        lista.add(5);
        lista.add(3);
        lista.add(6);
        lista.add(8);


        System.out.println("lista não ordenada: " + lista);

        Collections.sort(lista); //ordena automaticamente
        System.out.println(lista);

        for (int i = 0; i < lista.size(); i++) {
            for (int j = 0; j < lista.size() - 1; j++) {

         }
      }



    }
}

My class gets the values, 1, 5, 3, 6, 8! I know how a linked list works, so I'm using the linkedlist to save work! But how can I as a for loop and perhaps IFS conditions sort the list in ascending order?

I know that for ordering I will have to do ifs for comparison of the major and minor, but I wanted help on how to pass these values and how to work with them in the same class.

Thank you in advance.

I've got people, I think the code is simple and self explanatory enough

I also leave my thanks to @diegofm, you are fod4!

public class OrdenacaoTeste {
public static void ordenaLista(LinkedList<Integer> lista) {

}

public static void main(String[] args) {
    LinkedList<Integer> lista = new LinkedList<Integer>();

    lista.add(8);
    lista.add(9);
    lista.add(3);
    lista.add(5);
    lista.add(1);

    System.out.println("lista não ordenada: " + lista);

    for (int i = 0; i < lista.size() - 1; i++) { // percorro
        for (int j = 0; j < lista.size() - 1; j++) {
            if (lista.get(j) > lista.get(j + 1)) { // vejo se é maior que a
                                                    // prox posiçao
                Integer maior = lista.get(j);
                Integer menor = lista.get(j + 1);

                lista.remove(maior);
                lista.remove(menor);
                lista.add(j, menor);

                lista.add(j + 1, maior);
                // lista.remove(i);
            }
        }
        // Utilizando SORT
        // Collections.sort(lista);
        //System.out.println("Utilizando método sort" + lista);

        System.out.println("Lista ordenada em ordem crescente: " + lista); //imprimindo dentro do for
    }
    // System.out.println("Lista ordenada em ordem crescente" + lista); 
}

}
