Prerequisites for running JAR files Running JAR files on a Linux system requires the installation of the Java Runtime Environment (JRE), which is the basic component required to execute Java applications, including the Java Virtual Machine (JVM), core class libraries, etc. Many mainstream Linux distributions, such as Ubuntu, Debian, Fedora, openSUSE, etc., provide software libraries of JRE packages to facilitate user installation. The following article will detail the steps to install JRE on popular distributions. After setting up the JRE, you can choose to use the command line terminal or the graphical user interface to start the JAR file according to your personal preference. Your choice may depend on familiarity with Linux shells and personal preference

The oracle database requires jdk. The reasons are: 1. When using specific software or functions, other software or libraries included in the JDK are required; 2. Java JDK needs to be installed to run Java programs in the Oracle database; 3. JDK provides Develop and compile Java application functions; 4. Meet Oracle's requirements for Java functions to help implement and implement specific functions.

Deepin Linux system is a domestic operating system based on the Linux kernel. It has the characteristics of stability, security, and ease of use. In Deepin Linux system, installing JDK (Java Development Kit) is a necessary step for developing Java applications. This article will introduce in detail how to Install JDK in Deepin Linux system. Installation steps: Open the terminal of Deepin Linux system. Use the command line to download the JDK installation package. The command is as follows: ``shellsudoapt-getinstallopenjdk-11-jdk`` Wait for the download to complete and the system will automatically install the JDK. To verify whether the JDK is installed successfully, enter the following command: ```javaj

Key points and precautions for mastering JVM memory usage JVM (JavaVirtualMachine) is the environment in which Java applications run, and the most important one is the memory management of the JVM. Properly managing JVM memory can not only improve application performance, but also avoid problems such as memory leaks and memory overflows. This article will introduce the key points and considerations of JVM memory usage and provide some specific code examples. JVM memory partitions JVM memory is mainly divided into the following areas: Heap (He

This project is designed to facilitate developers to monitor multiple remote host JVMs faster. If your project is Spring boot, it is very easy to integrate. Just introduce the jar package. If it is not Spring boot, don’t be discouraged. You can quickly initialize a Spring boot program and introduce it yourself. Jar package is enough

JVM command line parameters allow you to adjust JVM behavior at a fine-grained level. The common parameters include: Set the Java heap size (-Xms, -Xmx) Set the new generation size (-Xmn) Enable the parallel garbage collector (-XX:+UseParallelGC) Reduce the memory usage of the Survivor area (-XX:-ReduceSurvivorSetInMemory) Eliminate redundancy Eliminate garbage collection (-XX:-EliminateRedundantGCs) Print garbage collection information (-XX:+PrintGC) Use the G1 garbage collector (-XX:-UseG1GC) Set the maximum garbage collection pause time (-XX:MaxGCPau

Java is a popular programming language. During the development of Java applications, you may encounter JVM memory overflow errors. This error usually causes the application to crash, affecting the user experience. This article will explore the causes of JVM memory overflow errors and how to deal with and avoid such errors. What is JVM memory overflow error? The Java Virtual Machine (JVM) is the running environment for Java applications. In the JVM, memory is divided into multiple areas, including heap, method area, stack, etc. The heap is used to store created objects

Detailed explanation of JVM principles: In-depth exploration of the working principle of the Java virtual machine requires specific code examples 1. Introduction With the rapid development and widespread application of the Java programming language, the Java Virtual Machine (JavaVirtualMachine, referred to as JVM) has also become indispensable in software development. a part of. As the running environment for Java programs, JVM can provide cross-platform features, allowing Java programs to run on different operating systems. In this article, we will delve into how the JVM works
