The main function of serialization in Java is to lossless the instance of a class, or it is through the Java serialization mechanism that instances of Java classes can be transmitted and retrieved through an object stream without damaging instances of the class. First, let's look at what class is a serialized class, The 1.A class itself implements the Serializable interface; The 2.A class itself does not implement the Serializable interface, but its parent class implements the class of the Seria

have "strong" personal views/opinions, preferences to try new technology. 6, Qualification certificate The qualification certificate is not the method that identifies the real programmer, MCSE, SCJP, the explanation is not what, they just let others know and obtain, at most represents this person to have certain knowledge in a certain technology. The original author wrote at the end of the article: the above-mentioned standards are not absolute, beca

method. This is because each method has its own weakness and application environment. Using these methods comprehensively makes Java program protection more effective. In addition, we often need other related security technologies, such as security authentication, digital signatures, and PKI.The example in this article is a Java application, which is a simulated test software for scjp (Sun certificate Java programmer. This application carries a large

It was not enough to stay in Shenzhen for two days. It was very convenient to return back and forth between Guangzhou and Shenzhen at. It took only one hour to build an intercity train, and the whole road was stable, it's quite comfortable. There are a lot of round trips, and there will be a trip in about 15 minutes, And the fare of 75 can be cheaper. Sun attended the training day in Shenzhen this time. In order to purchase the scjp exam at a prefere

movThese low-level things may not be used much as Java programmersHowever, it is helpful for you to understand the language.For example, the pointer in C is new in Java, which makes it much easier to understand new.I'm already sorry. Why didn't I have to learn these things well if I had to take over ten courses?Although I did this in the last semester ...... So far, no CET ~Hey ~~However, I have emphasized that CET is not the same as you, but English words must be well learned, at least these c

int to double Advantage of autoboxing and auto-unboxing is concise code. but careless use might result in poor performance of the Code. certain primitives are cached and autoboxing returns same wrapper objects. this value may depend on JVM used, normally this value are:1. The boolean values true and false.2. the byte values.3. The short and INT values between-128 and 127.4. the char values in the range '/u0000' to '/u007f '. It means, if limit bj1 = 127 and limit bj2 = 127 then limit bj1 = Limi

program code. The developer level is easier to be authenticated. Java has several professional certifications, such as scjp, scjd, and scwcd, which can be used to evaluate the basic skill of developers. In addition, scea and scbcd certification can evaluate the quality of the program architecture personnel. In addition to professional training, experience is also a condition for an excellent architect, and the program is also certified, such as PMP.

Let's first look at the R D personnel. I think the key to meeting the two factors of technology and process is people. How can we choose the right and right technology and have professional talents? How can we effectively manage the process? How to plan the system architecture that meets the five requirements of amrss

would not have an emergency landing? We simply cannot accept such doctors and pilots. So why should the software industry accept low-quality programmers?So what is the root cause of low-quality developers?3.

I often have my own personal research, hobbies, and projects, which are not written on my resume (which is generally not worth writing ), however, it may be his potential, depth, and stamina.

I haven't used the math class for a long time. I cannot remember it clearly, so that I can make mistakes when I read a scjp question. I will refresh my memory today. Remember!

combination of these methods, rather than a single use of one method. This is because each approach has its weaknesses and application environment. Using these methods in a comprehensive manner makes the protection of Java programs more efficient. In addition, we often need to use other related security, such as security certification, digital signature, PKI and so on.
