Defining an abstract attribute in a non-extabstracted class

I want to be able to instantiate an employee class (so this can’t be abstract) and have an abstract salary attribute that will be static for each type of employee.

I can do (in the working class):

private abstract int salario;

and in their subclasses:

private static int salario = x,

x being the value I want it to be for each subclass?

  • You are in the stack. Translate your question.

    You can’t, but if you explain why you want to do this, it might be possible to find an alternative.

  • You know that if you instantiate Gerente and that if Gerente inherit from Funcionario, then you will be instantiating a Funcionario, check?

If the intention is to prevent setSalario() you can put the setSalario method as private and call it next to the setCargo method()

Example

public class Funcionario{
    private float salario;
    private String cargo;

    public void setCargo(String cargo){
        this.cargo = cargo;
        setSalario();
    }

    private void setSalario(){
        if(this.cargo.equals("nomeDoCargo"){
            this.salario = <valor>;
        }
        else if(...){
           ...
        }
        ...
    }
}

Thus you protect the salary and only allow you to change if you change the position.
