Java Examples - Getting Thread Name - Tutorialspoint.
Because there are two thread objects, when you call this.getName() on the DrawThread object that is not the thread that is actually running so its name is not properly set. Only the wrapping thread's name is set. Inside of the DrawThread code, you should call Thread.currentThread().getName() to get the true name of the running thread.
The java.lang.Thread class provides methods to change and get the name of a thread. By default, each thread has a name i.e. thread-0, thread-1 and so on. By we can change the name of the thread by using setName() method. The syntax of setName() and getName() methods are given below.
A thread is a thread of execution in a program. The Java Virtual Machine allows an application to have multiple threads of execution running concurrently. Every thread has a priority. Threads with higher priority are executed in preference to threads with lower priority. Each thread may or may not also be marked as a daemon.

Creating a Thread in Java with Example Threads as we have discussed are light- weight smallest part of process that can perform tasks simultaneously with other threads of the same process. In this article we will discuss how to create thread with examples in Java.
The Thread class provides methods to change and get the name of a thread. By default, each thread has a name i.e. thread-0, thread-1 and so on. By we can change the name of the thread by using setName () method. The syntax of setName () and getName () methods are given below: public String getName (): is used to return the name of a thread.
Returns a string representation of this thread info. The format of this string depends on the implementation. The returned string will typically include the thread name, the thread ID, its state, and a stack trace if any.
A Simple Thread Example The simple example shown in full on the first page of this lesson defines two classes: SimpleThread and TwoThreadsTest. Let's begin our exploration of the application with the SimpleThread class--a subclass of the Thread class, which is provided by the java.lang package.
Java programming exercises and solution: Write a Java program to print 'Hello' on screen and then print your name on a separate line.
A thread is a program in execution that is performing some specific task. In Java, a thread is automatically created and started when the Java Virtual Machine(JVM) loads and this thread is called main thread. In order to execute a Java program, the main thread looks for the main() method in it. This thread is called main thread because the main() method of a Java program is the first method.
Write To a File. In the following example, we use the FileWriter class together with its write() method to write some text to the file we created in the example above. Note that when you are done writing to the file, you should close it with the close() method.
If a name isn't specified for a thread, it will be given a default name. A thread can be given a name in its constructor. In addition, it can be specified via a Thread object's setName() method. In addition, it should be noted that a thread is given an identification number that can be retrieved via the thread's getId() method. This thread doesn't change for the life of the thread, so that if.
