Objeto No para implementar a Lista Ligada.

public class No {
 int valor;
 String payload;
 No prox;
 No (int valor, String payload) {
  this.valor=valor;
  this.payload=payload;
 }
}

Implemente a interface Busca usando busca binária.

public interface Busca {
 /**retorna o indice do elemento que contém o valor buscado.*/
 int busca (int valorBuscado);
}

Implemente a interface Dicionario usando uma lista ligada

public interface Dicionario {

 /** Insere como primeiro elemento da lista. */
 void insere (int valor, String payload);
 /** Remove o elemento que contém o valor buscado, retorna o payload. 
  * Não pode "quebrar" a lista. */
 String remove (int valorBuscado);
 /** Busca o valor, retorna o payload ou null caso não encontre. */
 String busca (int valorBuscado);
 /** Imprime os elementos da lista. */
 void print ();
