"implements Runnable" vs. "extends Thread"
- When you extends Thread class, after that you can’t extend any other class which you required
Constructing the queue
Constructing the queue
- two ways of "normal" blocking queue
- a LinkedBlockingQueue, which uses a linked list as its internal structure and thus has no fixed capacity
- an ArrayBlockingQueue, which uses a fixed array and thus has a maximum capacity
- final: ArrayBlockingQueue with a bound
Pulling items off the queue
Pulling items off the queue
- run() method will starts a loop that continually takes the next item off the queue
- when there's no item on the queue, we need to wait for one to appear
- a trigger to shut down
- have it read with a timeout (
setSoTimeout())
- have it read with a timeout (

- use
Scannerif you want to parse specific type of token from a stream. - use
BufferedReaderif you want to get long strings from a stream - BufferedReader is synchronous while Scanner is not.

Parse Json With C#
Parse Json With C#
- http://wiki.unity3d.com/index.php/SimpleJSON
- To use SimpleJSON in C# you have to add this line at the top of your script:
using SimpleJSON;- Bug: StreamReader not accept string arguments --> 'string' cannot be converted to 'System.IO.Stream'
- https://stackoverflow.com/q/39484126
- Use a Stream as basic access to the file:
using(var fs = new FileStream("file.txt", FileMode.Open, FileAccess.Read)) using (var sr = new System.IO.StreamReader(fs)){ //Read file via sr.Read(), sr.ReadLine, ... }}- Since
StreamReaderandFileStreamimplementIDisposable, they will be disposed of because of the using clauses so you don't need to write a call.Close()or.Dispose()(As @TaW said).
