The replaceAll returns a String and does not change the current one. You need to do the following for your code to work:

String sal = "1500,32";
double salario = 0;
sal = sal.replaceAll(",", ".");
salario = Double.parseDouble(sal);

But keep in mind that there are better ways to convert monetary values.
