multithreading interview questions

Let's talk about some questions about the java programmer interview. This blog post is intended for recent graduates and java programmers who have been working for about two or three years. Why do I need to change jobs? This is a broad question. Everyone has an answer. For example: The company is not well-treated, The salary increase does not meet the expected requirements, Tired of the hard work of travel

If I want to learn it, I will leave without going in. Only by constantly learning can we keep up with the technology trend! Directory Question 01-10 [Sword refers to Offer learni

Java Multithreading interview question 1. What is the difference between a process and a thread?A process is a standalone (self contained) operating environment that can be viewed as a program or an application. A thread is a task that executes in a process. The Java Runtime environment is a single process that contains different classes and programs. Threads can be called lightweight processes. Threads req

create threads, how to create threads better (such as inheriting the thread class or calling the Runnable interface), and then gradually ask about concurrency problems like the Java memory model encountered in the process of Java concurrent programming, JDK1.5 introduces higher-order concurrency tools, common design patterns for concurrent programming, classic multithreading issues such as producer consumers, philosophers dining, reader-readers, or s

The purpose of multithreading is to maximize the utilization of CPU resources. Java writers run in the Java Virtual Machine (JVM), and within the JVM, the multitasking of the program is done through threads. Starting a Java application with Java commands starts a JVM process. In the same JVM process, there is only one process, which is itself.In this JVM environment, all program code runs as threads. A Java virtual machine allows an application to run

growth.Variables are changed and other threads can immediately know. There are several ways to ensure visibility: Volatile Variables added to the volatile keyword will be compiled with a lock prefix directive, which is equivalent to a memory barrier, the memory barrier can guarantee the order of memory operations. When a variable declared as volatile is written, the variable needs to write the data to main memory.Because the processor implements the cache consistency protocol, wri

the progress is updated, the progress bar is changed accordingly. If the progress is tracked by multiple threads, call the Invokeandwait () method to request the event dispatch thread to update the component accordingly. The Invokelater () method is called to update the component asynchronously.138, what is the busy loop in multi-threading?A busy loop is when a programmer uses a loop to wait for a thread, unlike the traditional method wait (), sleep () or yield (), which discards CPU control, a

(throughput) collector? The throughput collector uses a parallel version of the new generation garbage collector, which is used for medium-sized and large-scale data applications. The serial collector is sufficient for most small applications, which require about 100M of memory on modern processors. 41. In Java, when can objects be garbage collected? This object can be recycled when the object becomes inaccessible to applications that currently use the object. 42. Will garbage collection occur

1. What is a thread?A thread is the smallest unit that the operating system can perform operations on, which is included in the process and is the actual operating unit of the process. Programmers can use it for multiprocessor programming, and you can speed up operations-intensive tasks using multithreading. For example, if a thread takes 100 milliseconds to complete a task, it takes 10 milliseconds to complete the task with 10 threads.2. What is the
