    Question what is wrong with this code?

     public static void main(String[] args) {
            // TODO code application logic here
            Scanner in = new Scanner(System.in);
    	double a;
    	double b;
    	System.out.println("Dette program vil gøre så du kan sammenligne to tal og få forskellen af vide");
    	System.out.println("Vær sød at  skrive det første tal du vil sammenligne");
    	a=in.nextDouble();
    	System.out.println("Vær sød at skrive det andet tal du vil sammenligne");
    	b=in.nextDouble();
    	if (a == b);
    	System.out.println("De to tal er lige store");
            if else; <--- PROBLEM HERE
    	System.out.println("Det to tal er ikke lige store");

    se if else;. why is that wrong, it says: `(´ is expected

    illegal start of expression

    Executable statements must be inside a method. Where is your main() method?

    Review the if() and else/if statement construction. Ending an if() statement with a semi-colon ends the if statement before the code following. And there's no such statement is "if else;"

    Use a jar file not an exe file.
