style=\"font-weight: 400\"><strong>i)<\/strong> At first, we will download the package file from the official website.\u00a0 <\/span><br \/>\n<a href=\"https:\/\/www.oracle.com\/technetwork\/java\/javase\/downloads\/jdk8-downloads-2133151.html\" target=\"_blank\" rel=\"noopener\"><span style=\"font-weight:

different for 64-bit and 32-bit versions.<\/span><\/p>\n<p><span style=\"font-family: Verdana, Geneva, sans-serif\"><strong>ii)<\/strong> We will need some superuser privileges to install JDK. So we will use the <\/span>following<span style=\"font-family: Verdana, Geneva, sans-serif\"> command-<\/span><\/p>\n<pre class=\"EnlighterJSRAW\" data-enlighter-language=\"null\">sudo su<\/pre>\n<p><span style=\"font-weight: 400\"><strong>iii)<\/strong> The \/opt directory is actually reserved for all the software and add-on packages. This software is not part of the default installation. The command for creating a directory for JDK installation is-<\/span><\/p>\n<pre class=\"EnlighterJSRAW\" data-enlighter-language=\"null\">mkdir \/opt\/jdk<\/pre>\n<p><strong><a href=\"https:\/\/data-flair.training\/blogs\/java-frameworks\/\" target=\"_blank\" rel=\"noopener\">Follow this link to know about Java Frameworks<\/a><\/strong><\/p>\n<p><span style=\"font-family: Verdana, Geneva, sans-serif\"><strong>iv)<\/strong> Then we will extract Java into the \/opt\/<\/span>jdk<span style=\"font-family: Verdana, Geneva, sans-serif\"> directory:<\/span><\/p>\n<pre class=\"EnlighterJSRAW\" data-enlighter-language=\"null\">tar -zxf jdk-8u5-linux-x64.tar.gz -C \/opt\/jdk<\/pre>\n<p><span style=\"font-family: Verdana, Geneva, sans-serif\"><strong>v)<\/strong> Then we use the following command. This command verifies the file extraction into the \/opt\/<\/span>jdk<span style=\"font-family: Verdana, Geneva, sans-serif\"> directory.<\/span><\/p>\n<pre class=\"EnlighterJSRAW\" data-enlighter-language=\"null\">ls \/opt\/jdk<\/pre>\n<p><span style=\"font-family: Verdana, Geneva, sans-serif\"><strong>vi)<\/strong> By default, we can find the Java executable in \/opt\/<\/span>jdk<span style=\"font-family: Verdana, Geneva, sans-serif\">\/jdk1.8.0_05\/bin\/java directory. To set it as the default JVM we will use:<\/span><\/p>\n<pre class=\"EnlighterJSRAW\" data-enlighter-language=\"null\">update-alternatives --install \/usr\/bin\/java java \/opt\/jdk\/jdk1.8.0_05\/bin\/java 100\r\nupdate-alternatives --install \/usr\/bin\/javac javac \/opt\/jdk\/jdk1.8.0_05\/bin\/javac 100<\/pre>\n<p><span style=\"font-weight: 400\"><strong>vii)<\/strong> Then verify that Java has been successfully configured. Run the following command-<\/span><\/p>\n<pre class=\"EnlighterJSRAW\" data-enlighter-language=\"null\">update-alternatives --display java\r\nupdate-alternatives --display javac<\/pre>\n<p><span style=\"font-weight: 400\">We can check the installation by-<\/span><\/p>\n<pre class=\"EnlighterJSRAW\" data-enlighter-language=\"null\">java -version<\/pre>\n<p><span style=\"font-weight: 400\"><strong>viii)<\/strong> We can also update Java. Hence, download an updated version of Oracle&#8217;s website and extract to the \/opt\/jdk directory. After that, set it as the default JVM with a higher priority number:<\/span><\/p>\n<pre class=\"EnlighterJSRAW\" data-enlighter-language=\"null\">update-alternatives --install \/usr\/bin\/java java \/opt\/jdk\/jdk.new.version\/bin\/java 110\r\nupdate-alternatives --install \/usr\/bin\/javac javac \/opt\/jdk\/jdk.new.version\/bin\/javac 110<\/pre>\n<p>So, this was all about installing Java 8 in Ubuntu.
