Check the arrayList object at runtime

Question

I have an arraylist with three positions. I added to the array, objects like Manager, Seller and Technician, respectively. Using the getClass, would like to know how do I know which object is in each vector position.

I did it this way, but it didn’t make any mistakes and it didn’t call my methods.

public static void mostrarSalarioFuncionario() {

        ArrayList<Funcionario> listaFunc = new ArrayList<Funcionario>();
        listaFunc.add(ge);
        listaFunc.add(te);
        listaFunc.add(ve);
        System.out.println("CALCULO SALARIO DO FUNCIONARIO");
        for (int i = 0; i < listaFunc.size(); i++) {


            if (listaFunc.get(i).getClass().equals(ge) {
                System.out.println("Classe...:Gerente");
                System.out.println("Salário..:"+ge.calcularSalario());;
            }

            else if(listaFunc.get(i).getClass().equals(ve)) {
                System.out.println("Classe...:Vendedor");
                System.out.println("Salário..:"+ve.calcularSalario());;
            }

            else if (listaFunc.get(i).getClass().equals(te)) {
                System.out.println("Classe...:Técnico");
                System.out.println("Salário..:"+te.calcularSalario());
            }
}

Utilize instanceof to check the object subtype:

for (int i = 0; i < listaFunc.size(); i++) {

    System.out.println("Classe:"+listaFunc.get(i).getClass().getName().substring(32));
    if (listaFunc.get(i) instanceof Gerente) {
        System.out.println("Classe...:Gerente");
        System.out.println("Salário..:"+ge.calcularSalario());;
    }

    else if(listaFunc.get(i) instanceof Vendedor) {
        System.out.println("Classe...:Vendedor");
        System.out.println("Salário..:"+ve.calcularSalario());;
    }

    else if (listaFunc.get(i) instanceof Tecnico) {
        System.out.println("Classe...:Técnico");
        System.out.println("Salário..:"+te.calcularSalario());
    }
}
