method to initialize the array during declaration by including the initial value in braces. The following example shows how to initialize arrays of different types.Note: If the array is not initialized at the time of declaration, the array members will be automatically initialized to the default initial value of the array type. In addition, if an array is declared as a field of a certain type, it is set to the default value null when it is instantiated.

transmission and broadcastingOften said "send broadcast" and "receive", on the surface of broadcasting as an entity in the Android broadcasting mechanism, in fact, the entity itself is not in the so-called "broadcast" object exists, but with "intention" to express. Define the broadcast definition process, which is actually the corresponding broadcast "intention" of the definition process, and then send the "intention" by the broadcast sender. The OnReceive () function will be recalled after bei

You can omit the size of the array, as follows:

CREATE TABLE tag (id serial PRIMARY KEY, name TEXT not NULL);

INSERT into author (ID, name) VALUES (1, ' Pete Graham '), (2, ' Rachid Belaid '), (3, ' Robert Berry ');

pattern match is performed. When the Unicode data (nchar or
nvarchar data type) when using like, trailing spaces make sense. But for non-Unicode data
, trailing spaces have no meaning. Unicode like is compatible with the SQL-92 standard. ASCII like and SQL
Earlier versions of Server are compatible.
The following series of examples shows the rows returned by the ASCII like pattern match with the Unicode like pattern match

Anthropological studies were of interest to the family, so the researchers collected some family genealogy for research. In the experiment, the computer is used to process genealogy. To achieve this, the researchers converted the genealogy into a text file. The following is an example of a genealogy text file:

In 1994, Dr. Wenden Sove was selected as "the most fascinating 25 people" in the American People magazine. As a scientist, such a compliment surprised him. He said: "I do not think I am charming, but the internet was so charming, I was fortunate enough to glory." ”
Wenden Sove (Vinton Cerf) is a great scientist, Turing Award winner, President of the United States Presidential Medal of Freedom, Google's global vice president, but all of these titles added together, not "the father of the

This is not a very elegant design because the Web method above supports state change operations through HTTP get. In other words, the HTTP GET request has side effects. If the processing succeeds, the result of the request is to add a new user to the underlying data store--in this case, Robert
You can easily find many ways to set response-style response points, but these outdated design methods are based on the mainstream screen size, the effect is not ideal. In fact, there is no "mainstream" screen size of the concept. Another mainstream approach is to set the response point when the layout is broken. This method sounds better. But there are still questions, how do we judge if the layout is broken? One of the reasonable answers is to define the response point according to the classic
