Just a quick query - how much data (in bytes) do strings occupy? Does each character in a string take up one byte?
I attempted to look it up, but unfortunately ws schools didn't provide an answer...
I'm curious about this as I'm looking to minimize bandwidth usage in my web application.
On another note, for those who are familiar with it, does socket.io automatically convert data to JSON when using socket.emit()?
Characters in a string are stored as an array of characters. This means that the size of the string will be approximately sizeof(char) * noOfCharacters, without considering other factors within the String class at the moment. The size of each character can vary depending on the system and the type of characters being used, such as unicode characters which may take up 1 or 2 bytes.
However, it seems like you are specifically interested in how data is transmitted over a network. Keep in mind that data is always exchanged in bytes represented by byte[]. Therefore, strings need to be converted into a byte[] representation before they can be sent over the network.
To reduce bandwidth usage, options such as enabling compression or choosing interoperable serialization techniques like protobuf, smile, or fastinfoset can be considered.
