Exception Handling

[Arun Pai]

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 ;
}
Why this code from JQ+ does not compile?

[Valentin Crettaz]

What happens if you compile the code???

C:\testing>javac Test.java
Test.java:20: unreachable statement
return f ;
^
1 error

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.

Thanks Val. Now I am clear.
