Nowadays, Java technology is more widely used, broad market prospects, and higher salaries make Java engineers a very promising position.
So what can a java engineer do?
1. You can make a website
Java can be used to write websites. Now many large websites are written in JSP. The full name of JSP is Java Server Pages
It is a dynamic web page technology, such as the 163 we are familiar with. Some government websites are written using JSP.
2. Can do Android
Android is a free and open source operating system based on Linux, and its source code is Java.
So the mobile phone systems seen on the market, such as MIUI, Alibaba Cloud, Lewa, etc., all modify the source code and then release it.
Java for Android not only refers to the system, but also to APP. For more developers, they spend more time developing APP.
3. You can make games
Maybe you don’t know that when Nokia was still very popular, more than 90% of the mobile games you played were developed in Java of.
Of course, very few people are developing anymore, and they have all moved to Android.
There are also games developed in Java on computers. The most classic ones are: "Minecraft" (MC for short) and one of the most popular and influential online games in the world today, "League of Legends" (referred to as "League of Legends"). lol).
4. Software can be made
General programming languages can be used to make software, and Java is no exception, such as Eclipse, MyEclipse and other well-known Java development tools. About developing software Components, you can learn about Java Swing programming or awt related knowledge.
For example: Enterprise-level application development, here is the world of JAVA, ranging from large nationwide networked systems to small and medium-sized enterprise application solutions, Java occupies an extremely important position.
There is also the mobile field. The typical application is mobile games (mainly in this area in China). This is the world of J2ME. In fact, the scope of application is very wide.
Java has become the most popular programming software on the market today. In today's fast-developing world of information, Java technology is everywhere, including mobile software, mobile JAVA games, computer software, etc.
It can be said that as long as you use electronic products such as mobile phones and computers, you will use things related to Java.
5. Embedded: Write Once, Run Anywhere. The embedded field seems to be tailor-made for Java.
6. Big Data: Many Hadoop and other big data processing technologies use Java.
7. Scientific applications: Java’s security and portability give Java huge space in scientific applications, financial services, and more.
The above is the detailed content of What can a java engineer do. For more information, please follow other related articles on the PHP Chinese website!

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.

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.

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.
