Hello, everybody!

Again, i'm here to do some questions...

I have the following code...

public Map<String,Double> calculaFaturamentoMensal(){

		Double soma; 
		
		Map<String,Double> faturamentoMensal = new Map <String,Double>();
		
		for(MovimentoMes__c movimento : 
                   [Select m.Valor__c, m.Mes_de_Referencia__c From MovimentoMes__c m]){
			if(faturamentoMensal.containsKey(movimento.Mes_de_Referencia__c)){
				soma = 0;
				soma = faturamentoMensal.get(movimento.Mes_de_Referencia__c);
				soma += movimento.Valor__c;
				faturamentoMensal.put(movimento.Mes_de_Referencia__c,soma);
			} else {				           
                                faturamentoMensal.put
                                (movimento.Mes_de_Referencia__c,movimento.Valor__c);
			}
			
		}
		
		return faturamentoMensal;
	
	}

After this, i want to sort my map by the key... trying to ensure that when I iterate over the map ill have the values based on the crescent sequence of the key...

Tks for all
