Hi

I need some help to understand strictfp with interface. Hope some can explain using the following code sample, why I can able to use strictfp with Interface not with Interface Methods.

Interface with StrictFp( this compiles fine in Java 1.5)
--------------------------------------------------------
public strictfp interface checkForStrictFp{
public void isItPossible();
}

Interface with StrictFp and strictfp Method( this gives Compile error)
--------------------------------------------------------
public strictfp interface checkForStrictFp{
public strictfp void isItPossible();
}

C:\Tech\MyJava\checkForStrictFp.java:2: modifier strictfp not allowed here
public strictfp void isItPossible();
^
1 error

Tool completed with exit code 1

Anyone know, why I can't use strictfp with Interface method, which is nothing but "abstract" method.

In "abstract" class, if I had method with "strictfp" it compiles successfully.

Code sample:
------------
public abstract strictfp class checkForStrictFpWithAbstract{
public strictfp void isItPossible()
{
System.out.println("Strictfp confirms with IEEE 754");
}
}

Appreciate any help on this.

Thanks very much.

9.4 Abstract Method Declarations


Note that a method declared in an interface must not be declared strictfp or native or synchronized, or a compile-time error occurs, because those keywords describe implementation properties rather than interface properties. However, a method declared in an interface may be implemented by a method that is declared strictfp or native or synchronized in a class that implements the interface.
