double format in a toString

Hello, my problem is this: The exercise asks to print several values in Reais. After the tax calculations on top of this value (done on the object) I have toString printing the values, but it prints: msg += "\n\nTotal Impostos: R$" + totalImpostos() + "\nTotal Mercadorias: R$" + totalMercadorias() + "\nTotal Geral: R$" + totalGeral;

I wanted these values to be shown in R$ x.xx, at most two decimal places after the point. You have this possibility?

The exercise code was all done by me, so I’m not sure whether I’m right or not.

  • But if it’s monetary value because you’re using double?

  • I really don’t know which format is the right one, I missed classes of primitive types. Should I use float instead? Oh, I will check this question you sent. Thank you

  • If the format is in double, if the language of your component is in Brazilian Portuguese, you can use it like this: NumberFormat.getCurrencyInstance().format( 2 ), that he already shows just like this: R$ 2,00
