    Do you want your BiConsumer to call the method represented by your Method object? What's the signature of that Method?

  • Its a setter public void setValueBC(Double valueBC) { this.valueBC= valueBC; }

  • And you effectively want to call _notaFiscalServicoGeraServicosMovObject.setValueBC(doubleValue)?

  • that method is an example. I have a list with methods all with the same signature, the user choose the method and assign a value to it. I need to be able to call _notaFiscalServicoGeraServicosMovObject.setValueBC(doubleValue) or any other method that the user choose

Reset to default
2 
BiConsumer<_notaFiscalServicoGeraServicosMov, Double> consumer = (instance, param) -> {
    try {
        methodInstance.invoke(instance, new Object[] {param});
    } catch (LotsOfExceptionsHere e) {
        throw new RuntimeException(e);
    }
};

that should do it. There's no other way, really.

  • i've found that answer, but netbeans says: incompatible types: bad return type in lambda expression unexpected return value
