Sorry, what are applate, awt, swing, etc. used for in Java? I hope someone can explain it.
Sorry, what are applate, awt, swing, etc. used for in Java? I hope someone can explain it. 4 solutions #1 awt & swing are two kinds of UI libaray used in applete design #2 swing extends awt #3 Are there any books? #4 Applet is the client’s presentation layer interface, and SWing and AWT are actually user interface class libraries that implement the presentation layer. For example, if Applet is an application (such as OICQ), then the Swing and AWT libraries include buttons, scroll bars and other components needed to design this application.
Sorry, I don’t want to post an old post either. javaprivate attribute inheritance problem
public class Test extends A { public static void main(String[] args) { System.out.println(new Test().a); System.out.println(new Test().b); } } class A { private int a; } The error is reported as follows: The field A.a is not visible b cannot be resolved or is not a field Does this mean that private a is inherited? 38 solutions #1 Make your own sofa. I hope that after the reply is refreshed, I won’t criticize myself and realize that it is not a sofa. #2 How is it possible that private is private? #3 Quoting the reply from yewuqing007 on the 2nd floor: How is it possible that private is private? Specifically written for people who hold the same views as you. private is the access control character. I think the example in the post has fully proved that private can be inherited, but cannot be accessed directly. #4 Quoting the reply from the poster danliandejintou: Java code public class Test extends A { public static void main(String[] args) { System.out.println(new Test().a); System.out.println(new Test().b); } } class A { pr…… LZ Your code cannot be compiled, right? System.out.println(new Test().b); What’s going on with this sentence? Even if the sentence System.out.println(new Test().a); is excluded,…
A question about javamd5 encryption has been bothering me for many days. I beg you! ! ! (My community only has 50 points left, sorry)
I am revamping an asp website. When importing the original website data, I have trouble with password encryption: The original website is a 16-bit password encrypted with asp, but I don’t know how to encrypt it in java to the same password as my original asp. I have two questions here: 1. In java, we usually use things under java.security for encryption. Generally, no one implements the entire md5 encryption algorithm. Process, then I don’t know if the encryption method of asp is the same as the encryption method of java, and whether all md5 encryption results are the same Is it the same (if the number of digits after encryption is the same)? Whether it’s asp or java, or something else? 2. I am still wondering whether the encryption result of md5 can be artificially changed. I hope all the prawns will lend a helping hand to rescue this lost lamb of mine! I hope to get the code with the same encryption results of java md5 and asp md5. 7 solutions #1 The result is the same #2 Here is a Hash algorithm http://blog.csdn.net/fengfangfang/archive/2006/08/16/1068563.aspx #3 If the encryption results are the same, I want a java md5 encryption…

Sorry, I advise you not to learn AI easily! _Python Base Camp Blog
In the past two years, if you want to ask what technology is the hottest, I think someone will tell you: artificial intelligence. Although it has not yet reached the level of artificial intelligence robots in science fiction films, it has already been integrated into our lives and applied in various fields. Automatic driving, face recognition, speech recognition, question answering system, machine translation, personalized recommendation of various APPs, life bioscience, various predictions, etc., in fact, the core behind it is artificial intelligence. However, from the perspective of someone who has experienced it, I advise you not to learn AI easily. Because: its learning difficulty is indeed higher than other technologies! In the process of learning, these problems have appeared more or less: There are so many application directions, which one is the most suitable for you? I have read a lot of artificial intelligence courses, but the threshold is too high, and there are very few truly zero-based courses I have learned a lot of theoretical knowledge, but it is too difficult to find complete practical projects, they are all scattered exercises No one can help you when you encounter problems during self-study These are all manifestations of not having…
