Solutions: How to Fix Java Runtime Error Minecraft

Now that we’ve seen the strengths and weaknesses let’s focus on the main dish- the solutions. There are several possible reasons behind the Java runtime error, and therefore several different solutions for fixing it. We’ve compiled the most common fixes that work for most Minecraft players.

Solution 1: Installing the Latest Version of Java

One of the most significant reasons behind the Java runtime error is that you may have an older version of Java installed on your system, and Minecraft requires the latest version to function. To fix this, we can install the latest version of Java. Here’s how:

Steps Instructions
Step 1 Go to the official Java downloads web page from your computer’s web browser.
Step 2 Under the ‘Java Platform Standard Edition’ section, click on the ‘Download’ button for the latest Windows offline version of Java.
Step 3 Once the download is complete, run the setup file and follow the on-screen instructions to install Java onto your system.

Solution 2: Updating Java Parameters and Memory Allocation

If installing the latest version of Java did not resolve the issue, the problem may be that Minecraft is not receiving enough memory allocation. In this case, it is necessary to update certain Java parameters, including the amount of allocated memory. Follow these steps:

Steps Instructions
Step 1 Launch the Minecraft launcher, and from the profile drop-down menu, select ‘Edit Profile.’
Step 2 In the ‘Java Settings (Advanced)’ section, toggle the ‘JVM Arguments’ switch to ‘On.’
Step 3 In the ‘JVM Arguments’ text field, enter the following code: -Xmx2G -XX:+UnlockExperimentalVMOptions -XX:+UseG1GC -XX:G1NewSizePercent=20 -XX:G1ReservePercent=20 -XX:MaxGCPauseMillis=50 -XX:G1HeapRegionSize=32M. This code allows for 2GB of memory allocation, which should be sufficient to run Minecraft efficiently.

Solution 3: Updating Video Drivers

Another common reason why Minecraft players encounter runtime errors is due to outdated or corrupt video drivers, which can cause graphical errors. To avoid this, we must update our video drivers. Here’s how:

Step 2 In Device Manager, locate and right-click on your video card driver, and select ‘Update Driver.’
Step 3 Choose the ‘Search automatically for updated driver software’ option, and Windows will look for the latest version and install it automatically.

Solution 4: Reinstalling Minecraft

If none of the above solutions worked, then it may be necessary to reinstall Minecraft itself. Here’s how to go about doing this:

Steps Instructions
Step 1 Uninstall Minecraft by going to the ‘Control Panel’ and clicking on ‘Uninstall a program.’
Step 2 Delete the Minecraft folder located in your AppData directory.
Step 3 Download and install the latest version of Minecraft from the official website.
