How to create thread in Java 8

In this article, we'll see a new way to create thread in Java 8 and also revise the basic two ways to create thread with the help of lambda expression. Main focus of the topic is method reference and how to use thread with lambda expression. If you want to revise the basic concept of thread check this post and this post for lambda concept.


Creating a Thread in Java

The Java API makes it easy to work with threads. It lets you represent a thread as an object. An object of the  java.lang.Thread class represents a thread. Creating and using a thread in Java is as simple as creating an object of the Thread class and using that object in a program. Let’s start with the simplest example of creating a thread in Java. There are at least two steps involved in working with a thread:

  1. Creating an object of the Thread class
  2. Invoking the start() method of the Thread class to start the thread

Creating an object of the Thread class is the same as creating an object of any other classes in Java. In its simplest form, you can use the default constructor of the Thread class to create a Thread object.
// create a new thread
Thread simpleThread  = new Thread();

Creating an object of the Thread class allocates memory for that object on the heap. It does not start or run the thread. After you have created an object of the Thread class, you must call its start() method to start the thread represented by that object.
//start the thread
simpleThread.start();


Example 
The start() method returns after doing some housekeeping work. It puts the thread in the runnable state. In this state, the thread is ready to receive the CPU time. Note that invoking the start() method of a Thread object does not guarantee “when” this thread will start getting the CPU time. That is, it does not guarantee when the thread will start running. It just schedules the thread to receive the CPU time.



Three ways to create thread
There are three ways you can specify your code to be executed by a thread

  1. By inheriting your class from the Thread class
  2. By implementing the Runnable interface in your class
  3. By using the method reference to a method that takes no parameters and returns void


Inheriting Your Class from the Thread Class
When you inherit your class from the Thread class, you should override the run() method and provide the code to be executed by the thread.


Implementing the Runnable Interface
You can create a class that implements the java.lang.Runnable interface. Runnable is a functional interface and it is declared as follows

@FunctionalInterface
public interface Runnable



Using a Method Reference
Check this post for detail on method reference. From Java 8, you can use the method reference of a method of any class that takes no parameters and returns void as the code to be executed by a thread.

The following code declares a ThreadTest class that contains an execute() method. The method contains the code to be executed in a thread.


The thread will execute the code contained in the execute() method of the ThreadTest class

Final example

  15. Health Experts have proven that regular exercise coupled with a good diet allow you to live longer and healthier. In this busy day and age, not everyone has the time to go to the gym - resulting to a lot of overweight people that desperately need to exercise. A healthy alternative is for you to Buy Home Gym Equipments that you can store in your own home or even at your office. Here are some tips when buying home gym equipment.

    First, know your fitness goals and keep these goals in mind when you are buying home gym equipment. One of the biggest mistakes that people make is buying the biggest or trendiest fitness machine simply because they like how it looks. More often than not, these end up gathering dust in your storage rooms or garage because you never end up using them. It is important to take note of what particular type of physical activity you want or enjoy doing before you buy your exercise machine. If you are looking to loose a few pounds and you enjoy walking or hiking, a treadmill is the best option for you. If you are looking to tone your lower body while burning calories a stationary bike is your obvious choice. Similarly, Special Equipments for Core Strength Exercises, Strength Training Weight Vests, Core Strength & Abdominal Trainers, Home Cardio Training, Strength Training Power Cages, Strength Training Racks & More.

    Second, set aside a budget before Buying Home Gym Equipments. Quality exercise machines do not come cheap. They are constantly exposed to wear and tear when they are used properly.
