I'm trying to break the following ArrayList with a String :

  ArrayList<Funcionario> funcionarios = new ArrayList();

But when I instantiate the object, I add the values in there through my method and I try to use split , the compiler underlines the .split in red and gives error. I am trying to separate the information by a space " " .

Funcionario func = new Funcionario(); //Instancio o obj
func.cadastrar();  //CHama o método que lê o teclado
funcionarios.add(func); // Manda pro ArrayList
System.out.println("\n\n\nFuncionario cadastrado: \n" + func.toString()); //Mostra o que foi adicionado
System.in.read(); 
func.gravar(); //Salva em um txt
String[] separado = funcionarios.split(" "); //Aqui dá erro

Does anyone know what the error is?

I want to separate the registered information for each employee (name, e-mail, telephone, salary) in% with% s separated.

I want to break in String s to be able to add in a vector, sort and then be able to create a String sorted by name (in one of the application options) or salary (another part of the code).

Thank you

public String toString()
    {
        return    "\nNome: " + nome 
                + "\nEmail: " + email 
                + "\nTelefone: " + telefone 
                + "\nSalario: R$ " + salario ;
    }

Try this:

List<Funcionario> funcionarios = new ArrayList<>();
SortedSet<Funcionario> funcionariosPorNome = new TreeSet<>(Comparator.comparing(Funcionario::getNome));
SortedSet<Funcionario> funcionariosPorSalario = new TreeSet<>(Comparator.comparingDouble(Funcionario::getSalario));
SortedSet<Funcionario> funcionariosPorEmail = new TreeSet<>(Comparator.comparing(Funcionario::getEmail));
SortedSet<Funcionario> funcionariosPorTelefone = new TreeSet<>(Comparator.comparing(Funcionario::getTelefone));

Funcionario func = new Funcionario(); //Instancio o obj
func.cadastrar();  //Chama o método que lê o teclado
funcionarios.add(func); // Manda pro ArrayList
System.out.println("\n\n\nFuncionario cadastrado: \n" + func.toString()); //Mostra o que foi adicionado
System.in.read(); 
func.gravar(); //Salva em um txt
funcionariosPorNome.add(func);
funcionariosPorSalario.add(func);
funcionariosPorEmail.add(func);
funcionariosPorTelefone.add(func);

If this is not what you want, then please edit the question to make it clear in the text what it is you want.

If you want to get employees sorted by different fields you do not need to make these separations. From List<Funcionario> you can sort it as you want.

List<Funcionario> funcionarios = new ArrayList<>();
func.cadastrar();  //CHama o método que lê o teclado
funcionarios.add(func); // Manda pro ArrayList
System.out.println("\n\n\nFuncionario cadastrado: \n" + func.toString()); //Mostra o que foi adicionado
System.in.read(); 
func.gravar(); //Salva em um txt

Sort by name:

Collections.sort(funcionarios, new Comparator<Funcionario>(){

    public int compare(Funcionario f1, Funcionario f2){

        return f1.nome.compareTo(f2.nome);

    }

});

Sorts by salary:

Collections.sort(funcionarios, new Comparator<Funcionario>(){

    public int compare(Funcionario f1, Funcionario f2){

        return f1.salario.compareTo(f2.salario);

    }

});

You are trying to separate an object with split (). This generates compilation error because this method separates only String. Try this funcionarios.toString().split(" "); , but in the split see what to use to separate.
