In fact you can... By creating a third method : public void method(Object o) { if (o instanceof Integer) { method((Integer)o); } else if (o instanceof String) { method((String)o); } else { System.err.println("Error, 'o' is not an Integer nor a String..."); } } The point is that if you create a new method public void method (Long l) { } you must change the method(Object o) to add this possibility. so if you really want to go over this problem, you can write : public void method(Object o) { Class c = o.getClass(); try { Method meth = this.getClass.getDeclaredMethod("method", new Class[]{c}); } catch (NoSuchMethodException e) { System.err.println("Error, 'o' is not a supported Object... Its class is : " + o.getClass()); e.printStackTrace(); return; } meth.invoke(this, new Object[]{o}); } this code assumes that the methods "method" are inner methods of the current object ("this", as it is referenced to get the Method object, and to invoke it).

I'd find the "this." prefix strange though, as it somewhat violates data encapsulation; It makes an object aware of itself _among others_ (I am special, I am "this"). This is meta-information that only the programmer or higher level objects should be aware of. A common technique is to identify class variables by underscore suffix. See for instance http://geosoft.no/development/javastyle.html rule #8. Be careful with variable name _prefixes_ (such as "m" or "_" etc.) as they tend to reduce the readability of the name. A side effect of the name suffix is that it nicely resolves the problem of finding good variable names for setter methods: void setName (String name) { name_ = name; } ========================================================================== TOPIC: Process.destroy() on Win32 http://groups-beta.google.com/group/comp.lang.java.programmer/browse_thread/thread/2677bdb23c8cb84b ========================================================================== == 1 of 1 == Date: Fri, Aug 27 2004 5:18 pm From: Paul Lutus <[EMAIL PROTECTED]> Joshua Jones wrote: > Running on Win2k.

Using named inner classes for such tasks creates extra work: you define and instantiate them in different places, and they still don't need more than one member function to call the API of your business model layer. IMHO, this is the cause for the tediousness. [...] > I am just curious as to what the current consensus is on this topic. > From an OO standpoint? From a supportability standpoint? Cleanliness? > Access standpoint? My opinions on the matter: OO: Don't locate the support classes in a different package. In fact, because of the minimal content required, inner classes are ideal. Supportability: Using anonymous inner classes defines a simple class with (often) one method right where it's used. And since such code is not often reused -- a GUI rarely has several buttons that do exactly the same -- there is no code duplication. Cleanliness: For me an anonymous inner class is a clear winner to handle events in a GUI: - it's s simple construct for a trivial task (calling your business model layer to perform business logic) - it does almost nothing, so it doesn't interrupt the flow of the code - Since it's anonymous, there only is the public API of it's interface and/or superclass. Also, it can only access method parameters or final members of the defining class. Thus there are no problems of accessing too much or too little information. Access: Your original inner classes are a good idea. So are anonymous inner classes. -- Oscar Kind http://home.hccnet.nl/okind/ Software Developer for contact information, see website PGP Key fingerprint: 91F3 6C72 F465 5E98 C246 61D9 2C32 8E24 097B B4E2 ========================================================================== TOPIC: Synchronized Not Working http://groups-beta.google.com/group/comp.lang.java.programmer/browse_thread/thread/58d8bf5c4828ced5 ========================================================================== == 1 of 1 == Date: Fri, Aug 27 2004 8:00 pm From: "Tony Morris" <[EMAIL PROTECTED]> Is the method called on the same instance (which acts as the mutex) ?

This time I came soo close. My main problem is where I have indicated with (---) in the second else if condition. If you remove && j< (----) from it and test it, you will see exactly what I am talking about. If I replace(----)with m, where m is an int m=n; and then put m--; after j++; at the end of the outer loop, it does not work. I would appreciate your help with this. Also, I have a few questions below the code I need help with: int n=7,marker=(n/2)+1,i=1,j=1; while(i<=n) { while(j<=n) { if((i<marker)&&((marker-i)<j && j <(marker+i))) {System.out.print("*");} else if((i==marker)) {System.out.print("*");} else if((i>marker)&&((i-marker)<j && j < (----))) {System.out.print("*");} else {System.out.print(" ");} j++; } System.out.println(""); i++; j=1; } - In Java, if say I print out 7 rows of stars and at the end I want to go back to the very beginning of the first line, or any other line apart from the last one,how do I do that? - My guess is that (boolean)?(true):(false); is some sort of a condensed if-else clause. If so, is there a limit on the lines of code that one can put in place of the (true) and the (false)? - If say, 5 rows of dots are printed using System.out.print(ln), to the screen, is it possible to create a second code that traverses the dots and removes or erases some of them as I wish? - Does the Java API provide any info on ALL Java operators and symbols? I would appreciate your help.Thanks..

I think the example is clear and concise, and that jikes is being too picky. This seems to be a common alternative: line = in.readLine(); while (line != null) { // do some stuff with line [...] line = in.readLine(); } ...but I find it unnecessarily verbose, and the logic isn't quite as clear when code is repeated outside and inside the loop. This is especially true when the missing stuff, which could be long, gets filled in.
