How can I increase the memory allocated to the Java Virtual Machine to resolve this error?

You can modify the JVM's maximum heap size by using the `-Xmx` parameter when launching your Java application. For example, `-Xmx2g` allocates 2GB of memory. Edit the launch script or configuration file (e.g., for IntelliJ IDEA, modify the VM options in the Run/Debug Configurations). Ensure your system has enough physical RAM to support the increased allocation.
