public float parseFloat(String s)
{
float f = 0.0f;
try
{
f = Float.valueOf(s).floatValue();
return f ;
}
catch(NumberFormatException nfe)
{
System.out.println("Invalid input " + s);
f = Float.NaN ;
return f;
}
finally { System.out.println("finally"); }
return f ;
}

What happens if you compile the code???

The return statement after the finally block is not reachable because there already is a return statement in the try and another one in the catch block. So whatever happens, one of those two will be executed and the one outside is unreachable.
