JavaSE is a standard version and is the basic part of Java. However, various subsequent frameworks and products are all based on JavaSE, which means that JavaSE is the basis for the upward development of Java. , the underlying foundation of any advanced Java product is JavaSE, so if you want to learn it, it is necessary to learn it solidly and firmly.
Java SE (Java Platform, Standard Edition). Java SE was formerly known as J2SE. It allows the development and deployment of Java applications for use in desktop, server, embedded and real-time environments. Java SE contains classes that support Java Web services development and provides the foundation for Java Platform, Enterprise Edition (Java EE).
In short, after learning javase, you can learn javaWEB, such as servlet, jsp, listener, filter, etc., then learn the ssh framework, that is, struts2 spring hibernate, and then you can learn EJB3.0, such as JMS, JNDI, JAP, etc.
The above is the detailed content of What will you learn after studying javase?. For more information, please follow other related articles on the PHP Chinese website!
How does platform independence benefit enterprise-level Java applications?May 03, 2025 am 12:23 AMJava 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.

What are the advantages of using Java for web applications that need to run on different servers?May 03, 2025 am 12:13 AMJava 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.
How does the JVM contribute to Java's 'write once, run anywhere' (WORA) capability?May 02, 2025 am 12:25 AMJVM 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.
How do newer versions of Java address platform-specific issues?May 02, 2025 am 12:18 AMThe 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.
Explain the process of bytecode verification performed by the JVM.May 02, 2025 am 12:18 AMThe 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.
