Java remains a popular programming language to this day. It may be old, but it hasn’t lost its user base or its usefulness over the years. Many developers continue to use it and it is in active development. Language changes and enhancements are made all the time, making building and running Java-based applications incredibly easy.
The solution could not create a Java virtual machine
The “Java virtual machine could not be created” error usually occurs when compiling code in an IDE. The error is not descriptive enough to point users to the exact problem; however, it is usually the result of;
- The wrong version of Java is being used
- The wrong version of the SDK was installed
- Wrong environment variables were set
- Syntax errors when declaring which version of Java to use
- Libraries are missing in IDE
- Errors in memory management
The solution will vary depending on the underlying cause. Please try the following.
1. Check the supported Java version
The message Could not create Java virtual machine typically appears when code is compiled into an IDE. This is because the IDE is not compatible with the version of Java installed on your system.
Check which versions of Java your IDE supports. Then check which version of Java is installed and make sure it is compatible with the supported version. If not, install the correct version.
2. Check environment variables
Java parameters that are set in environment variables in Windows 10 can cause the error Could not create Java virtual machine.
- Open File Explorer.
- paste this explorer shell:::{BB06C0E4-D293-4f75-8A90-CB05B6477EEE}into the location bar and tap Enter.
- Click Advanced System Settingson the left panel.
- Go to the Advanced Guide.
- Select environmental variablesand click New under System variables.
- body r _JAVA_OPTIONS in the name field.
- On the way / value, type: -Xmx1024M
- Click OK.
- Restart the app.
Also, you need to make sure that the correct path is provided to the Java SDK.
- Open File Explorer and go to C: Java Program Files
- Open the folder for the JDK versionyou want to use.
- Copy the path to the folder.
- Open environment variables(see previous steps).
- Under System variables, select JAVA_HOME.
- Click Edit.
- Enter the pathyou copied and click OK.
3. Check the boot arguments
Check the initialization arguments that have been set. You may have the correct version of Java installed, but the initialization arguments may have set the version that will be used to compile for something else. If you did a Java update in place, the initialization arguments are most likely still referencing the previous version.
4. Check the syntax
For any arguments entered, verify that the syntax is correct. The slightest error can result in the error Could not create Java virtual machine. Look for an additional script or an incorrect version that was declared.
5. Reinstall Java
Try reinstalling Java. This can solve problems you may have when opening an IDE or similar application.
- Open Control Panel.
- We go to Programs> Uninstall a program.
- Look towards Java and select it.
- Click on the Uninstall Button at the top.
- Allow Java to be uninstalled.
- Download and install java again from here .
6. Check memory allocation
One of the main reasons you get the Cannot create Java virtual machine error is if the memory allocated for its use is insufficient.
- Open File Explorer.
- We go to C:Program FilesJava
- Open the JDK Folder with the currently installed version number.
- Find a file called exe and run it.
- The application will provide a GUI for memory management.
- Please increase the amount of memory and try again.
conclusion
Setting up a development environment can often be time consuming. There are many components that must be configured and requirements that must be met before developing or compiling code. These errors are not unique to Java, as all languages have their own set of requirements that must be met in order to be used.
