The compiler is saying that the statement is unreachable on the line with the if statement. I'm not overly familiar with Java.

public double calculate()
{
  total_usage_charge = getUsageCharge();
  total_charge = rate + total_usage_charge;

  return total_charge;

  if("A".equals(package_plan.toUpperCase()) && getUsageCharge() > 14.95)
  {
    sB = getUsageCharge() - 14.95;
    System.out.println("You're spending more money than you should. If you switched to Plan B you would save:$" + sB);
  }
}

Because you're returning from the method by executing this:

return total_charge;

So the next statement is never going to be executed.

You return (return total_charge;) from your method just before the if statement. No code after a return can ever be executed (except the relevant finally block if your return statement is located in a try...catch...finally).

You are returning before calling if statement so its unreacheable .

A method returns to the code that invoked it when it reaches a return statement.

return total_charge;

You method returns at this point, post which any code won't be reachable.

you have putted return statement above IF. so when compiler comes on this statement everytime it returns from there and if can not executed anytime so, remove returns statement or put it below if Condition.

Code will not be executed after return statement.following block of code is causing problem i.e. 

return total_charge;

So you will have to remove this line or put it at the end.!

Just like that ;)

        }**

Did u meant to comment it, if yes do it right. or this is error and unreachable statement according to the code provided.

Comment it with /* your code to comment */
