How to get a pthread-based multithreaded program working in Java

The following tutorial will show you how to build a Java program with the help of pthreads.

pthread will be used for all the communication between threads and the execution of the program.

Before going further, it’s important to take a look at the following points: Pthreads is a new library which is not yet in the Java platform.

It is still in beta, so we are not certain how it will perform in the long term.

We will use a sample program in the next section to demonstrate this point.

This example shows how to get some basic information about a user.

For the purpose of this tutorial, we are going to use the User class as a model.

The following code is the main class: public class User extends Thread { private final int threadCount; private final String name; public User(int threadCount, String name) { this.threadCount = threadCount + 1; this.name = name; } public String getName() { return name;} } The constructor of the User object looks like this: private final static int threadCounter = 0; private static final String NAME = “User”; private static void main(String[] args) { User user = new User(); threadCounter++; } The threadCounter variable will hold the counter of the thread in which the thread is running.

The name property is a reference to the current thread.

This is the name of the current user.

In the following code, we check the name property, which is set to User , and then call the getName method of the new User object.

user.getName(); In this example, we can see that the threadCounter is incremented whenever the user is created.

The thread counter will always be incremented in the following manner: When a thread starts, the thread counter is set.

When a new thread is created, the counter is increments.

The next time the user thread is started, the value of threadCounter will be increments again.

When the thread runs out of threads, the number of threads will decrease.

The getName call will return the current User object, which in this case is the User instance which is created in the first place.

The user instance is the thread object which has been created in Java 8.

If you are using Java 9, you will see that this is no longer the case.

The Thread class is now used as the base class for all other threads in your program.

The class has many methods and properties, but the most important of these is Thread.currentThread().

The thread.currentLoop() method, which returns a new Thread object, is the only method that has changed since Java 8 to Java 9.

When you call Thread.start() or Thread.sleep() in Java 9 and Java 8, they are still called as in Java 7.

You should not use this method in Java 10 and Java 9 unless you have explicitly told the compiler to use Thread.

currentLoop() .

Thread.stop() and Thread.group() are the same methods that you use in Java 6.

The new Thread class has the following methods: void setThreadState(int state) Sets the thread state.

void close() Removes the thread.

void stop() Stops the thread and closes it. void getState() Returns the current state.

private static int getThreadCount() Returns one of the integer values returned by Thread.get() .

private static String getThreadName() Returns a String representing the current Thread.

private void getThread(int i) Returns the Thread object.

private int thread Counter() Returns counter of thread counter in the currentThread() method.

private String threadName() Return the current name of thread.

private final Thread threadCounter() Returns thread counter of threads counter in Thread.count() method of Thread.set() method and in Thread().stop() method respectively.

public static void threadCounter(int counter) Called whenever the current counter is negative, so that it is incremental.

public int threadCurrentThreadCounter() Called whenever counter is positive.

public String threadCounterName() Gets the name given by ThreadCounter to the thread currently running.

public void Thread.join() Called when a new program is started.

private boolean threadInProgress() Called whether thread is in progress.

private Thread currentThread () Called whenever current thread is present in the stack.

private List threads () Returns a List of all threads currently running in the program’s stack.

public boolean isThreadInProgress(int currentThreadCounter) Returns whether the current stack is full.

public User user() Returns an instance of User.

private java.lang.

Object[] getUsers() Returns array of User objects.

private long count() Returns number of currently active users in the system.

public Thread[] getCurrentThread() Returns current thread counter.

public long getCount() Return number of users currently active in
