The has recently started using idea to write Java projects, which is very popular and much more convenient than eclipse. More functions, relative to the use of the complexity is also higher, because many of the online use and create a project simple tutorial, are based on the old version, each new version has a different line, for the use of small white, this is still difficult to follow this tutorial step
The following is transferred from http://ifeve.com/creating-and-starting-java-threads/:The Java thread class is also an object class, and its instances are inherited from Java.lang.Thread or its subclasses. You can create a thread in Java in the following ways:New Thread ();Executing the thread can invoke the start ()
I. Thread life cycle and five basic statesFor the life cycle of the threads in Java, first look at this more classic diagram:Java threads have v basic statenew State (new): when the thread object pair is created, it enters the new state, such as thread t = new MyThread ();ready State (Runnable): when calling the Thread object's start () method (T.start ();). The thread enters the ready state. A thread in the ready state simply means that the thread is
1. Concept Because Java is completely object-oriented, in Java, we are talking about a thread that is an instance object of the thread class. So, a thread is an object, it has its own fields and methods. 2. Creating ThreadsThere are 2 ways to create a thread: 1, the thread class of the extended threading parent class, and 2, the implementation of the Runnable int
If you are already using Java programming and have used any popular framework like spring and hibernate, you should be very familiar with the use of annotations. When working with an existing framework, it is usually sufficient to use its annotations. But do you sometimes have the need to create your own annotations?
Not long ago, I found a reason to create an a
Recently in the study of Java knowledge, through the Internet to look at the information, found that the original understanding of something not deep, gradually understand some. The use of objects, in the process of writing software is necessary, do not know whether people like me, almost all use new to create. So, the question is, how many ways does Java have to

One, there are three main ways to create threads in Java:1. Inherit the thread class to create a threading class(1) Define a subclass of the thread class and override the Run method of the class, which represents the task that the thread will complete. So the run () method is called the actuator.(2) Create an instance
The Java thread class is also an object class, and its instances are inherited from Java.lang.Thread or its subclasses. You can create a thread in Java in the following way, and the thread can invoke the start () method of that thread:Tread thread = new Thread ();Thread.Start ();In the example above, we did not run the code for the thread, so the thread terminate
reference variable is defined (that is, a pointer is set), and the reference variable does not point to any valid memory. Therefore, you cannot specify the length of an array when defining an array. And since the definition array is just a reference variable and does not point to any valid memory space, there is no memory space to store the array elements, so this array is not available and can only be used if the array is initialized.
2, one-dimensional array creation

We often say that Java is an object-oriented language, so almost all operations in Java are inseparable from objects. In the Java language, the most common way to create objects is through calls to the class constructor, but there are several other ways to create objects.1)

After performing the callable task, you can get a future object, call get on the object to get to the callable task returned object, and combined with the thread pool interface Executorservice can realize the legend has the return result of multithreading.Since three ways can be used to create multi-threading, and three ways to implement the principle of the first

There are two ways to create Java threads:
1. By inheriting the thread class, overriding the thread's run () method, where the threads run logically
2. Instantiate the thread class by implementing the Runnable interface
