Vaadin Grid

-
Grid in vaadin is used to represent the data as we do in table in html so grid is the way to represent the  data in vaadin so mainly grid is a vaadin component.

Grid has a header footer Row and Column to represent data .

First of all to represent a data we need a data so that for that we can take a simple Array list.

List<food> myfood = Arrays.asList(new food("maggie", 1),
    new food("pasta", 2),
    new food("pizza",3)); // this we got the data to present


Now initializing a Grid in vaadin same is the way as in ArrayList.
Grid<food>=new Grid<>();// Taking Grid
grid.setItems(myfood); // given here the array of Food


grid.addColumn(food::getfoodName).setCaption("FoodName");
grid.addColumn(qty::getfoodqty).setCaption("FoodQty");


layout.addComponent(grid);


grid.setSelectionMode(SelectionMode.MULTI);// can also add if we want select the


multiple columns

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
