Introduction to appletviewer

                                          appletviewer


As discussed in the previous post that what is appletviewer lets revise back again an appletviewer is a tool to view how our applet will look like by setting the size again and again we can check instantly that how it will appear.

Why the use of appletviewer..?

Every time the rule is to make an applet first extend the applet class that is inheritance and compile it a class file is produced with the byte code and and now the second step is open the notepad and write applet tag as stated in the previous post and save as .htm extension.
 In the applet tag we have to provide a class file name . Last step is go in file menu and select our html file and open in browser the output is seen.

The meaning is that whenever changes are to be made all this steps are to be performed again so becomes a tedious job to perform all this and as a plus point to the java users java provided appletviewer it is a code nothing else .

Here comes a big difference between the original steps mentioned above and in appletviewer the difference is as before we were maintaining two files one was the java file and other is the html file here we have to maintain only one file that is the java file.

Question arises how one file..?
The key is that you have to include that applet tag in the java file then again comes an  error when we compile so the key is include that in comment line that means  particular applet  tag and what is the work of appletviewer the work is it finds all the comment line and finds the aapplet tag written in the html structure.

So now no need to make two seperate file just include the applet tag in the java file first compile the java file it will be compiled as the applet tag included in it is in comment and then in the command line type 

                                  aapletviewer javafilenm //not class file name

Your output will be ready ......!!

That was all about appletviewer hope the readers might have understood from the depth what is the use of appletviewer.

State space search / blocks world problem by heuristic approach /TIC TAC TOE

-
A lot of AI is about SEARCH. The "state space" is the set of states of the problem we can get to by applying operators to a state of the problem to get a new state. A  state  contains  all of the information necessary to predict the effects of an action and to determine if it is a goal state. State-space searching assumes that the agent has perfect knowledge of the state space and can observe what state it is in (i.e., there is full observability); the agent has a set of actions that have known deterministic effects;some states are goal states, the agent wants to reach one of these goal states, and the agent can recognize a goal state. a solution is a sequence of actions that will get the agent from its current state to a goal state. Define the Problem as State Space Search Consider the problem of “Playing Chess” . to build a program that could play chess, we have to specify the starting position of the chess board, the rules that define legal moves. And the

Navigation in Vaadin.

-
Plain Vaadin applications do not have normal web page navigation as they usually run on a single page, as all Ajax applications do. Quite commonly, however, applications have different views between which the user should be able to navigate. The  Navigator  in Vaadin can be used for most cases of navigation. Views managed by the navigator automatically get a distinct URI fragment, which can be used to be able to bookmark the views and their states and to go back and forward in the browser history. The  Navigator  class manages a collection of  views  that implement the  View  interface. SO the class in which you are defining Navigation must implement with a  View  interface. addView() i s the method by which you can register Your View . You can add your view at any point ,Your View must have   name identifier and be added to a  View . Once registered, you can navigate to them with  navigateTo() . Navigator  manages navigation in a component container, which can be
