You should not have issues if you do not include Java SE13 in your path and you do not change the Java home. Keep Java 1.8 as it is and only use Java 13 with Netbeans.

<div>
You can of course use 13 from the command line if you do<br />

<pre><code class="code-1 nolinks" id="code-20-43093109-1"><span>set PATH=&quot;&lt;put the 13 install directory here without the angle brackets&gt;;%PATH%&quot;</span>
</code></pre>
Then you can check with<br />

<pre><code class="code-1 nolinks" id="code-20-43093109-2"><span>java -version</span>
</code></pre>

Thanks experts. I get the idea you are talking about, but I am still a little confused. CEHJ, are you saying that the following steps should work:<br><br>1. Download and Install Java SE13<br><strong>2. set PATH="&lt;put the 13 install directory here without the angle brackets&gt;;%PATH%" </strong><br>3. Install NetBeans IDE<br>4. Reboot the computer and all should work well.<br><br><br>

You do say that but the asker did not understand it.<br><br><blockquote>4. Reboot the computer and all should work well. </blockquote><br>The asker assumed that it would work after a restart, which is only true if you set it as environment variable (not from the command line).This is why I clarified it.

Ah, i see. Yes - thanks for that

I want to install Java SE13 on my laptop. However I am wondering if their might be an issue, because if I go to my Users directory and type java -version then I get version 1.8.0_241-b07<br />
<br />
So will their be a conflict if I install Java SE13 and java version 1.8.0_241-b07 has already been installed?<br />
Note that I will also be installing netbeans as my code IDE.<br />
<br />
Example in DOS:<br />
C:\Users\Walter&gt;java -version<br />
java version &quot;1.8.0_241&quot;<br />
Java(TM) SE Runtime Environment (build 1.80.0_241-b07)<br />

Installing Java SE13

Virtualization is the act of creating a virtual (rather than actual) version of something, including (but not limited to) a virtual computer hardware platform, operating system (OS), storage device, or computer network resources. Virtualization is usually the creation of a system that executes separate from the underlying hardware resources, or the creation of an entire desktop for systems located elsewhere, similar to thin clients.

Virtualization

Java is a platform-independent, object-oriented programming language and run-time environment, designed to have as few implementation dependencies as possible such that developers can write one set of code across all platforms using libraries. Most devices will not run Java natively, and require a run-time component to be installed in order to execute a Java program.

Installation is the act of making a computer program program ready for execution. Because the process varies programs often come with a specialized program responsible for doing whatever is needed for their installation. Installation may be part of a larger software deployment process. Cross platform installer builders that produce installers for Windows, Mac OS X and Linux include InstallAnywhere, InstallBuilder and Install4J. Installers for Microsoft Windows include Windows Installer, InstallShield, and Wise Installation Studio; free installer-authoring tools include NSIS, IzPack, Clickteam, InnoSetup, InstallSimple and WiX. Mac OS X includes Installer, and also includes a separate software updating application.

Installation

Golang, also called Go, is an open source programming language that is a statically-typed language with syntax loosely derived from C, adding automatic memory management, type safety, some dynamic-typing capabilities, additional built-in types such as variable-length arrays and key-value maps, and a large standard library. Go is a general-purpose systems programming language that aims to be efficient both for development and execution with a focus on fast compilation and increased maintainability of large projects. Go was originally targeted at systems programming tasks such as building server/web applications, high throughput middleware and databases.
