In-depth analysis of Java, .NET, and Web application characteristics

In this survey, developers engaged in Java development accounted for 51.27% of the total survey respondents, so this also makes the survey on the use of Java language relatively more accurate. The survey results show that among Java developers, the most used JDK versions are JDK1.6 and JDK1.7, and the usage rate of these two versions accounts for 88.26% of the total survey data. In terms of the use of application servers, Tomcat is mainly used for Java development, accounting for up to 75%. Oracle Weblogic, which ranks second, has 10.12%, while Jboss AS and IBM Websphere only have 4.35% and 5.48% respectively. In addition, the vast majority of developers do not use other languages on the JVM, and this proportion is as high as 72.87%. The top two Java web development frameworks used by Java developers are Spring MVC and Struts (used by 36.66% and 25.79% respectively), and the use of these two accounts for 62.45% of the total share. There are also two points to pay attention to. One is that the proportion of these Java developers who do not use frameworks has reached 11.54%, and the second is that the proportion of self-developed frameworks has reached 10.91%. The top four Java technology hotspots that have attracted much attention are Struts+Spring+Hibernate, Hadoop, new features in Java8 and Spring MVC. Among them, Struts+Spring+Hibernate and Hadoop have a similar proportion, and their attention levels are 26.05% and 26.05%, respectively. 26.00%, new features in Java 8 are 16.11%, and Spring MVC is 11.37%. In terms of development tools, the development tools used by the vast majority of Java developers are Eclipse, and IntelliJ IDEA also has a small number of users. In addition, regardless of the length of development years, Eclipse occupies the absolute dominance of Java development tools. However, as the development years increase, Eclipse's share decreases, while the proportions of Intelli JIDEA and NetBeans increase.

How does session hijacking work and how can you mitigate it in PHP?
Apr 06, 2025 am 12:02 AM
Session hijacking can be achieved through the following steps: 1. Obtain the session ID, 2. Use the session ID, 3. Keep the session active. The methods to prevent session hijacking in PHP include: 1. Use the session_regenerate_id() function to regenerate the session ID, 2. Store session data through the database, 3. Ensure that all session data is transmitted through HTTPS.
Explain different error types in PHP (Notice, Warning, Fatal Error, Parse Error).
Apr 08, 2025 am 12:03 AM
There are four main error types in PHP: 1.Notice: the slightest, will not interrupt the program, such as accessing undefined variables; 2. Warning: serious than Notice, will not terminate the program, such as containing no files; 3. FatalError: the most serious, will terminate the program, such as calling no function; 4. ParseError: syntax error, will prevent the program from being executed, such as forgetting to add the end tag.

What are HTTP request methods (GET, POST, PUT, DELETE, etc.) and when should each be used?
Apr 09, 2025 am 12:09 AM
HTTP request methods include GET, POST, PUT and DELETE, which are used to obtain, submit, update and delete resources respectively. 1. The GET method is used to obtain resources and is suitable for read operations. 2. The POST method is used to submit data and is often used to create new resources. 3. The PUT method is used to update resources and is suitable for complete updates. 4. The DELETE method is used to delete resources and is suitable for deletion operations.
Explain secure password hashing in PHP (e.g., password_hash, password_verify). Why not use MD5 or SHA1?
Apr 17, 2025 am 12:06 AM
In PHP, password_hash and password_verify functions should be used to implement secure password hashing, and MD5 or SHA1 should not be used. 1) password_hash generates a hash containing salt values to enhance security. 2) Password_verify verify password and ensure security by comparing hash values. 3) MD5 and SHA1 are vulnerable and lack salt values, and are not suitable for modern password security.
PHP: A Key Language for Web Development
Apr 13, 2025 am 12:08 AM
PHP is a scripting language widely used on the server side, especially suitable for web development. 1.PHP can embed HTML, process HTTP requests and responses, and supports a variety of databases. 2.PHP is used to generate dynamic web content, process form data, access databases, etc., with strong community support and open source resources. 3. PHP is an interpreted language, and the execution process includes lexical analysis, grammatical analysis, compilation and execution. 4.PHP can be combined with MySQL for advanced applications such as user registration systems. 5. When debugging PHP, you can use functions such as error_reporting() and var_dump(). 6. Optimize PHP code to use caching mechanisms, optimize database queries and use built-in functions. 7
Explain Arrow Functions (short closures) introduced in PHP 7.4.
Apr 06, 2025 am 12:01 AM
The arrow function was introduced in PHP7.4 and is a simplified form of short closures. 1) They are defined using the => operator, omitting function and use keywords. 2) The arrow function automatically captures the current scope variable without the use keyword. 3) They are often used in callback functions and short calculations to improve code simplicity and readability.
