Leave this field empty. Basic Authentication in Spring WebClient. It is a text-based, human-readable format for representing simple data structures and associative arrays called objects.

The JSON format is often used for transmitting structured data over a network connection in a process called serialization. Its main application is in AJAX web application programming, where it serves as an alternative to the traditional use of the XML format.

I am using sockets to connect my Android application client and a Java backend Server. From the client I would like to send two variables of data each time I communicate with the server.

Having read the data on the server side and made an appropriate conclusion, I would like to return a single message to the client.

I think I will be okay with this. So my two questions are how can I establish that the two Strings being sent client to server are unique on the client side and how can I separate these two Strings on the server side. I was thinking an array of Strings, but could not establish if this was possible or appropriate.

I assume you are using TCP sockets for the client-server interaction? One way to send different types of data to the server and have it be able to differentiate between the two is to dedicate the first byte or more if you have more than types of messages as some kind of identifier.

If the first byte is one, then it is message A, if its 2, then its message B. This makes it possible for readUTF to find the end of the encoded string.

If you decide on your own record structure then you should make sure that the end and type of the record is either known or detectable. Learn more. Using Sockets to send and receive data Ask Question.

The Overflow Blog.You can work directly with JSON data contained in file-system files by creating an external table that exposes it to the database.

For better performance, you can load the external-table data into an ordinary table. The database handles this check constraint the same as any other check constraint — it enforces rules about the content of the column. Update operations on a document in a JSON column require the replacement of the entire document. You can make fine-grained modifications to a JSON document, but when you need to save the changes to disk the entire updated document is written.

From an application-development perspective this makes sense: If a JSON document is used to record application state, the application typically retrieves it, modifies it, and then writes it back to disk, to reflect the updated state.

You typically do not want your application to deal with the complexity of tracking piece-wise updates to documents and then writing them back to the database. The same is true of updating such a column. Example is a partial example of this. External tables make it easy to access JSON documents that are stored as separate files in a file system.

Each file can be exposed to Oracle Database as a row in an external table. An external table can also provide access to the content of a dump file produced by a NoSQL database.

You can use an external table of JSON documents to, in effect, query the data in file-system files directly. This can be useful if you need only process the data from all of the files in a one-time operation.

But if you instead need to make multiple queries of the documents, and especially if different queries select data from different rows of the external table different documentsthen for better performance consider copying the data from the external table into an ordinary database table, using an INSERT as SELECT statement — see Example Once the JSON data has been loaded into a JSON column of an ordinary table, you can index the content, and then you can efficiently query the data in a repetitive, selective way.

It lets you create and store collections of documents of any kind not just JSONretrieve them, and query them, without needing to know how the documents are stored in the database.
