monitoring service, you need to specify the type of event you want to receive file change notifications. The registered directory returns a Watchkey instance key. Perform an infinite loop to monitor the events to come. When an event occurs, the instance key is signaled and placed in the watcher queue. Get the key instance back from the watcher queue. The Key instance contains the name of the file where the change occurred. Get the suspended events from the key instance and process t

First, the state of the threadBefore we formally learn the specific methods in the thread class, let's look at the state of the thread, which will help to understand the methods in the thread class.Threads go through a number of States, from creation to eventual extinction. In general, threads include the following states: Create (new), Ready (runnable), run (running), block (blocked), time waiting, waiting, extinction (dead).When a new thread is need

1 // discover Asset Primary key 2 @Id3 @GeneratedValue (generator= "System-uuid")4 @ Genericgenerator (name= "System-uuid", strategy= "UUID")5 private Long ID; 　　The GUID is a 128-bit long number, typically represented by a 16 binary. The core idea of the algorithm is to combine the machine's NIC, local time, and a random number to generate the GUID. Theoretically, if a machine produces 10 million GUIDs per second, it can be guaranteed

// randomly generates an integer between 1~100 int randomnumber = (int) (Math.random () * +) + 1; System.out.println (randomnumber);This is a method of generating random numbers directly using the Math.random () method.There is also a way to use the random class.Random (): Creates a new random number generator.Random (Long Seed): Creates a new random number generator with a single long seed.The first method of construction is to use the

callback function method is to use the function pointer. In Java, however, pointers are not supported, so there is a command pattern, an object-oriented version of this callback mechanism. Command mode is used to encapsulate an order/request, and, simply put, a command object contains a sequence of actions (statements) to be executed to perform a specific task. Of course, not a random statement sequence can constitute a command object, according to

1. Application Scenarios for the futureIn concurrent programming, we often use non-blocking models, in the previous multi-threaded three implementations, whether inheriting the thread class or implementing the Runnable interface, there is no guarantee to get to the previous execution results. By implementing the callback interface and using the future to receive multi-threaded execution results.The future represents the result of an asynchronous task

Recently learned Map-reduce principle and map-reduce programming, Ushun with learning under Java programming, for Java commonly used data structure and class set, I summarize to mind diagram, easy to clarify the relationship between each otherPackage Leiji;Import java.util.ArrayList;Import java.util.List;Import java.ut

Good things to share to recommend, here to recommend a Java platform under the open-source diagram of the library Jfreechart, related resources (source code, demo source, development Guide) has been uploaded to the CSDN resources, need to download them yourself.Jfreechart's charting capabilities are very powerful, covering almost any chart you want, and it's cool to draw. Look at the main jfreechart:Before

appears some problem solution. However, we generally refer to the design pattern, usually refers to the Gof classic book, "Designing Pattern--elements of the reusable object-oriented Software," the 23 patterns, thus, It is the specific needle for object-oriented software design process. In the overall sense, the pattern represents a language, a documented experience, or even a culture. Often a lot of inconvenient description, or describe a very complex problem, using the pattern language to na

Collection Framework (collection Origin and collection inheritance system diagram)* A: The origin of the collection* The array length is fixed, when the added element exceeds the length of the array needs to be redefined, too cumbersome, Java provides us with a collection class, can store arbitrary objects, the length can be changed, as the element increases, and

Java has been learning before, the basics are not forgotten, and these high-level languages are too similar, so those data types, or loop control flow, as well as standard equipment, and so on is just skip it.However, some important concepts will be interspersed in the introduction of the article.So, these articles are suitable for those who have a certain level of advanced object-oriented language basis for reading.We first write a student

StringBuffer is a thread-safe, variable sequence of characters. It inherits from Abstractstringbuilder and implements the Charsequence interface.StringBuilder is also a subclass of Abstractstringbuilder, but StringBuilder and stringbuffer are not thread-safe, the latter are thread-safe.The diagram between StringBuffer and Charsequence is as follows: The StringBuffer class, like String, is also used to re

Defined A queue is a special linear table that allows for deletion only on the front end of the table, and on the back end of the table.The LinkedList class implements the queue interface, so we can use the LinkedList as a queue.Legend The queue itself is a first-in, first-out model (FIFO) that is very similar to the queuing model in our daily life. Depending on the implementation, they mainly have the array and the list of two implementat

1. What is a class set framework1. is a set of classes and interfaces2. Located in the Java.util package3. Primarily for users to store and manage objects4. Divided into three main categories--collections, lists and mappings2.

. 　　If the program is in a single-threaded environment, or if access is done only in one thread, it is more efficient to consider non-synchronous classes, and if multiple threads may operate on a class at the same time, the synchronized classes should be used. 　　Pay special attention to the operation of the hash table, and the object as key should correctly replicate the Equals and Hashcode methods. Try to return the interface rather than the actual
