When a thread pool thread blocks, the thread pool creates additional threads, and the time and memory resources required to create, destroy, and schedule threads is very expensive And when many developers see that they have threads in their program that are not doing anything useful, they tend to create more threads in hopes that the new threads will do something useful The key to building scalable and responsive applications is to not block the threads you have so that they can be used and reused to execute other tasks 26, Compute-Bound Asynchronous Operations, focused on how to use existing threads to perform compute-bound operations, and 27, I/O-Bound Asynchronous Operations, focused on how to use threads when performing I/O-bound operations In this chapter, I focus on thread synchronization Thread synchronization is used to prevent corruption when multiple threads access shared data at the same time . 131.107.2.11/16 how to read image from pdf file using java PDFBox: Extract Content From a PDF Using Java - DZone Java

1 Answer. image.scaleToFit(595, 842); image.setAbsolutePosition(0, 0); doc.add(image); doc.newPage(); Document doc = new Document(new Rectangle(image.getScaledWidth(), image.getScaledHeight())); // create a writer, open the document image.setAbsolutePosition(0, 0); doc.add(image); doc.newPage(); I emphasize at the same time because thread synchronization is all about timing If you have some data that is accessed by two threads and those threads cannot possibly touch the data simultaneously, then thread synchronization is not required at all In 27, I showed some code that implements a named-pipe server In the ClientConnected method, a thread allocates a Byte[] that will be filled with the data being sent from the client When the client sends the data, a different thread pool thread will execute the GotRequest method, and this method will process the data in the Byte[] Here we have two different threads accessing the same data But the application is architected in such a way that it is impossible for two threads to access this same Byte[] at the same time Therefore, no thread synchronization is used in the named-pipe application at all . 131.107.2.12/16 empid ordmonth qty 1 1 1 1 1 1 1 1 1 1 ... 2 2 2 2 2 2 2 2 2 2 ... 1996-07 1996-08 1996-09 1996-10 1996-11 1996-12 1997-01 1997-02 1997-03 1997-04 ... 1996-07 1996-08 1996-09 1996-10 1996-11 1996-12 1997-01 1997-02 1997-03 1997-04 ... 121 247 255 143 318 536 304 168 275 20 ... 50 94 137 248 237 319 230 36 151 468 ... This is ideal because thread synchronization has many problems associated with it First, it is tedious and extremely error-prone In your code, you must identify all data that could potentially be touched by multiple threads at the same time Then you must surround this code with additional code that acquires and releases a thread synchronization lock The lock ensures that only one thread at a time can access the resource If you forget to surround just.
