Memo for beginners to learn Java (4)

Having said so much, I haven’t written down several basic functions of threads. Now let’s supplement

start a thread
T1=new YourThread();
T1.start()

operate threads
T1.run() , As mentioned before, starting the thread will automatically perform this operation

Suspend
T1.suspend()//It is different from Sleep(), it means suspending a thread without setting a time
Corresponding to suspension, we also You can reactivate a thread
T1.resume()

Stop the thread
T1.stop()//But it does not destroy the thread

Test whether the thread is activated
T1.isAlive()//This is a function, returned It is a Boolean value

Enter network programming: Sockets
See how much I can understand from memory: Sockets are in the session layer of the seven-layer protocol. Its job is to tell the application that it is going to send information to the network and hide the sending details. Open For example, when we make a phone call, we only need to dial the number, pick up the receiver, and speak. We don’t need to care about how our voice is transmitted to the other party through the phone line. Sockets are the phone, and all the secrets are It's all in this phone.

I took a preliminary look at the concept of Sockets, and it seems that there are some things in the programs involved that I haven’t touched yet, so I’ll put them aside first.

How does platform independence benefit enterprise-level Java applications?How does platform independence benefit enterprise-level Java applications?May 03, 2025 am 12:23 AM

Java is widely used in enterprise-level applications because of its platform independence. 1) Platform independence is implemented through Java virtual machine (JVM), so that the code can run on any platform that supports Java. 2) It simplifies cross-platform deployment and development processes, providing greater flexibility and scalability. 3) However, it is necessary to pay attention to performance differences and third-party library compatibility and adopt best practices such as using pure Java code and cross-platform testing.

Java is suitable for developing cross-server web applications. 1) Java's "write once, run everywhere" philosophy makes its code run on any platform that supports JVM. 2) Java has a rich ecosystem, including tools such as Spring and Hibernate, to simplify the development process. 3) Java performs excellently in performance and security, providing efficient memory management and strong security guarantees.

How does the JVM contribute to Java's 'write once, run anywhere' (WORA) capability?How does the JVM contribute to Java's 'write once, run anywhere' (WORA) capability?May 02, 2025 am 12:25 AM

JVM implements the WORA features of Java through bytecode interpretation, platform-independent APIs and dynamic class loading: 1. Bytecode is interpreted as machine code to ensure cross-platform operation; 2. Standard API abstract operating system differences; 3. Classes are loaded dynamically at runtime to ensure consistency.

How do newer versions of Java address platform-specific issues?How do newer versions of Java address platform-specific issues?May 02, 2025 am 12:18 AM

The latest version of Java effectively solves platform-specific problems through JVM optimization, standard library improvements and third-party library support. 1) JVM optimization, such as Java11's ZGC improves garbage collection performance. 2) Standard library improvements, such as Java9's module system reducing platform-related problems. 3) Third-party libraries provide platform-optimized versions, such as OpenCV.

The JVM's bytecode verification process includes four key steps: 1) Check whether the class file format complies with the specifications, 2) Verify the validity and correctness of the bytecode instructions, 3) Perform data flow analysis to ensure type safety, and 4) Balancing the thoroughness and performance of verification. Through these steps, the JVM ensures that only secure, correct bytecode is executed, thereby protecting the integrity and security of the program.

SecLists

SecLists is the ultimate security tester's companion. It is a collection of various types of lists that are frequently used during security assessments, all in one place. SecLists helps make security testing more efficient and productive by conveniently providing all the lists a security tester might need. List types include usernames, passwords, URLs, fuzzing payloads, sensitive data patterns, web shells, and more. The tester can simply pull this repository onto a new test machine and he will have access to every type of list he needs.
