class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Java is a widely used programming language essential for various applications, from enterprise software to mobile apps. With the release of Ubuntu 24.04, users now have better access to the latest versions of Java through its repositories and package manager. This guide covers all you need to install and configure the latest Java version on Ubuntu 24.04, including the most recent Long Term Support (LTS) version, OpenJDK 21, as well as Oracle\u2019s proprietary JDK.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Why_Java_Installation_is_Important_for_Ubuntu_2404_Users\"><\/span><strong>Why Java Installation is Important for Ubuntu 24.04 Users<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Ubuntu 24.04 is a powerful choice for developers and system administrators alike, and Java\u2019s versatility and platform independence make it a necessary component in many development environments. Installing Java on Ubuntu allows you to run applications that depend on Java runtime environments (JRE), set up development tools, and deploy Java-based software on <a href=\"https:\/\/www.blueangel.host\/offshore-server.html\">servers<\/a>.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Step_1_Check_if_Java_is_Already_Installed_on_Ubuntu_2404\"><\/span><strong>Step 1: Check if Java is Already Installed on Ubuntu 24.04<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>Before installing Java, let\u2019s check if it\u2019s already present. Open your terminal and run:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>java -version<\/code><\/pre>\n\n\n\n<p>If Java is installed, this command will display the version number (e.g., <code>openjdk version \"21.0.0\"<\/code>). If Java isn\u2019t installed, you\u2019ll see an error message stating the command was not found.<\/p>\n\n\n\n<p>For additional confirmation, you can also check the Java compiler:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>javac -version<\/code><\/pre>\n\n\n\n<p>This checks if the Java Development Kit (JDK) is installed, as the compiler (<code>javac<\/code>) is included only in JDK packages, not JRE packages.<\/p>\n\n\n\n<p>If Java isn\u2019t installed, or you want to update to the latest version, follow the steps below.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Step_2_Installing_OpenJDK_21_on_Ubuntu_2404\"><\/span><strong>Step 2: Installing OpenJDK 21 on Ubuntu 24.04<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>OpenJDK is the open-source implementation of the Java Platform, widely used due to its stability and compatibility.

However, due to licensing restrictions, Oracle JDK is not available in Ubuntu\u2019s default repositories.
