So I am working on an assignment where I have to have a print method in a constructor that displays a distance. I also have to have three separate get methods depending on what the input is in the demo class. My question is that I am trying to write the print method to contain a decision structure based on which get is used.
public void prt()
{
DecimalFormat formatter = new DecimalFormat("#,##0.00");
System.out.println("The time it takes the sound to travel " + distance +
" feet through air is " + if (getSpeedInAir() > 0)
{
formatter.format(getSpeedInAir());
}
else if (getSpeedInWater() > 0)
{
formatter.format(getSpeedInWater());
}
else if (getSpeedInSteel() > 0)
{
formatter.format(getSpeedInSteel());
}
else
"error";)
}
After trying to compile I am getting the following errors.

Any help on why this is happening would be greatly appreciated.
