What are the instance methods of JAVA thread? What are the class methods

Instance methods are:

checkAccess()

Determine whether the currently running thread has the right to modify the thread.

getContextClassLoader()

Return the context ClassLoader of this thread.

getId()

Return the identifier of the thread

getName()

Return the name of the thread.

getPriority()

Return the priority of the thread.

isAlive()

Test whether the thread is active.

start()

In order to help the thread that has not been started yet start executing, we need to call the run method of the thread to start it. In this way, the Java virtual machine will start executing the tasks of the thread.

run()

If the thread is constructed through an independent Runnable running object, then call the run method of the Runnable object. If not, the method does nothing and returns.

. . . . etc

Class method:

The most commonly used ones are

sleep(long millis)

In order to help players who have not passed the level yet, let us learn about the specific puzzle solving methods. In the game, we need to pay attention to the environment and use various props and clues to solve puzzles. Sometimes, we need to trigger certain events in a specific order or combination of specific items. In addition, talking to NPCs is also a way to obtain important clues.

In order to help everyone better understand the sleep(long millis, int nanos) method, let’s discuss the specific usage.

In order to help players understand better, let us learn about the specific operation methods of thread sleep. In Java, we can use the Thread.sleep() method to temporarily sleep for a period of time in the currently executing thread. This method accepts a parameter indicating the number of milliseconds and nanoseconds the thread sleeps. By calling this method, we can let the thread pause execution for a specified period of time so that we can perform some other operations. hope

currentThread()

Returns a reference to the currently executing thread object.

yield()

Pause the currently executing thread object and execute other threads.

. . . . etc

To help everyone understand better, let us take a look at the code of a TestRunnable class that implements the Runnable interface: ```java public class TestRunnable implements Runnable { //Implement the run() method of the Runnable interface here public void run() { //Write specific task logic code here } } ``` The above is the definition of a simple TestRunnable class, which implements the Runnable interface and overrides the run() method. In the run() method, you can write specific task logic code. Hopefully this simple example will

private int i ;

public void run() {

for( ; i

In order to help players who have not passed the level yet, let us learn about the specific methods of solving the puzzle! In the game, we need to pay attention to the following points: 1. Observe the scene carefully and collect clues. Look at the surrounding objects, words, patterns, etc., they may hide key information. 2. Try to interact with items in the scene. Click, drag, and combine items to find ways to trigger events or solve puzzles. 3. Think about logic and reasoning. Sometimes, solving puzzles requires us to use reasoning and logic

Let us take a look at the specific implementation of the main method: public static void main(String[] args) {

int i = 0;

for(; i

In order to help players who have not passed the level yet, let us learn about the specific puzzle solving methods. Next, we can use the following code to print the name of the current thread and the value of variable i for debugging and troubleshooting: "System.out.println(Thread.currentThread().getName() " " i);". In this way, we can better understand the execution process of the program.

if(i == 10){

We can create an instance of a runnable class named `TestRunnable` through the following line of code: ```java TestRunnable tr = new TestRunnable(); ``` This line of code will instantiate the `TestRunnable` class and assign it to the `tr` variable. This will allow us to use `tr` to call methods in the `TestRunnable` class or access its properties.

In order to help players who have not passed the level yet, let us learn about the specific puzzle solving methods. In code, we can use the following method to create and start a child thread: ``` new Thread(tr, "child thread 0").start(); ``` Through this method, we can create a new sub-thread outside the main thread and name it "Sub-thread 0". In this way, we can perform some time-consuming operations in the child thread without blocking

How many ways does java implement a thread?

Expand All

There are basically two types:

The first is to inherit Tread class:

The following is a sample code for a thread class named PrimeThread: ```java class PrimeThread extends Thread { long minPrime; PrimeThread(long minPrime) { this.minPrime = minPrime; } public void run() { // Compute larger prime numbers after minPrime... } } ``` This thread class can be used to calculate prime numbers greater than a given minPrime value. In the run method, you can write the logic of prime number calculation. By creating and starting multiple PrimeThread threads, multiple prime number calculation tasks can be performed simultaneously.

In main:

Let's look at an example using the PrimeThread class to calculate and print out the prime number 143. Here is the code: ```java PrimeThread p = new PrimeThread(143); p.start(); ``` In this example, we create a PrimeThread object p and pass 143 as a parameter to its constructor. Then, we call p's start() method to start the thread. Next, the PrimeThread class will perform calculations in the background and print out the prime number 143.

In order to help players who have not passed the level yet, let us learn about the specific puzzle solving methods. In addition, there is another way to solve puzzles by implementing the Runnable interface. Let’s explore together!

The following is a simple Java code example that uses the Runnable interface to create a thread and output "Hello from a thread!". ```java public class HelloRunnable implements Runnable { public void run() { System.out.println("Hello from a thread!"); } public static void main(String[] args) { new Thread(new HelloRunnable()).start(); } } ``` The above code creates a HelloRunnable class, implements the Runnable interface, and outputs a message in the run() method. In the main() method, we create a new thread and start it. This thread will execute the run() method of the HelloRunnable object and output the corresponding message. In this way, we can see the "Hello from a thread!" output on the console. Hope the above answers can help you!

You can also use xxx.start() to run this thread

To help developers who have not yet mastered thread management, let us learn how to manage thread pools. You can use Executor and ExecutorService in Java to implement thread pool management. If you need more examples and details, it is recommended that you go to Oracle's official website to find relevant information.
