JVM What are the common problems?

Common JVM problems include: 1. Memory leak, 2. Garbage collection pause, 3. Class loading problems, 4. Memory overflow errors, 5. Performance bottlenecks. Solutions to these problems include using tools to detect memory leaks, adjusting garbage collector settings, ensuring the classpath is correctly configured, adjusting JVM memory settings, and optimizing JVM performance configuration.

Top 10 Java Features That Make It a Powerful Language

The 10 core features of Java include: 1) garbage collection, which reduces the burden on developers through automatic memory management; 2) platform independence, and realizes "write once, run everywhere" through bytecode; 3) object-oriented programming, supporting encapsulation, inheritance and polymorphism; 4) robust exception handling, providing a try-catch-finally mechanism; 5) multi-threading support, simplifying concurrent programming; 6) collection framework, providing efficient data structures and algorithms; 7) database connections, standardizing database operations; 8) JavaBeans, promoting the development of reusable components; 9) annotation, enhancing code metadata management; 10) Lambda expressions and stream APIs, introducing the concept of functional programming.

What is Java mainly for? Analysis of the main uses of Java in actual development

Java is mainly used to build desktop applications, mobile applications, enterprise-level solutions and big data processing. 1. Enterprise-level applications: Support complex applications such as banking systems through JavaEE. 2. Web development: Use Spring and Hibernate to simplify development, and SpringBoot quickly builds microservices. 3. Mobile applications: Still one of the main languages ??for Android development. 4. Big data processing: Hadoop and Spark process massive data based on Java. 5. Game development: suitable for small and medium-sized game development, such as Minecraft.
