inaccurate, post data is not limited, the limit is the processing capacity of the server handler.The security of the 3.POST is higher than the security of get. Note: The security described here is not the same concept as the "security" mentioned in get above. The meaning of "security" above is simply not to make data changes, and the meaning of security here is the meaning of true security, such as: submit data through get, user name and password will appear in plaintext on the URL, because (1)

Java Interview SummaryObject-oriented programming (OOP)Java is a computer programming language that supports concurrency, class-based, and object-oriented. The advantages of object-oriented software development are listed below: Code development is modular and easier to maintain and modify. Code reuse.

53 Java Thread Surface questionsHere are some popular interview questions about Java threading, which you can use to prepare for the interview.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 operat

encounters io blocking, because IO is implemented by the operating system, Java code has no way of directly contacting the operating system8. How do I get to the thread dump file in Java?The purpose of the dump file:Dead loop, deadlock, blocking, page open slow and so on, hitting thread dump is the best way to solve the problem. Therefore, thread dump is also the thread stack.Gets the contents of the dump

, which gives me absolute control over the lock. Multi-use sync class less wait and notifyFirst, Countdownlatch, Semaphore, Cyclicbarrier, and Exchanger, these synchronization classes simplify coding operations, and it is difficult to control complex control flows with wait and notify. Second, these classes are written and maintained by the best companies in the subsequent JDK and they will continue to be optimized and perfected, using these highe

serialized. For example, when a class that implements the serializable interface is serialized to Objectstream, a variable of type transient is not written to the stream, and the value of the corresponding variable is null when deserializing back.Question: Which containers use the border layout as their default layout?Answer: Window, Frame, Dialog.Question: How to understand what synchronization is?Answer: Synchronization is used to control the access of shared resources across multiple threads

client. The expression is defined between the two tags, 9. What does the implied object mean? What are the hidden objects?JSP implied objects are some Java objects in the page, and the JSP container allows these Java objects to be used by developers. Developers can use them directly without a clear statement. JSP implicit objects are also called predefined variables. The following lists the implied objects

, exceptions are the way that Java communicates to you about systems and programs that are wrong. In Java, the exception function is to implement classes such as Throwable,exception,runtimeexception, and then some keywords to deal with anomalies, such as Throw,throws,try,catch,Finally and the like. All the anomalies are derived from throwable. Throwable further divides the error into java.lang.Exception and
