The error “error: could not find or load main class” occurs when the Java Virtual Machine (JVM) fails to locate the main class specified in the program argument. This error can be due to various reasons related to the classpath configuration, including incorrect classpath settings, missing or misconfigured Manifest files, or problems with the classloading process. To resolve this error, developers need to ensure that the correct classpath is set and that all necessary dependencies and libraries are available to the JVM during execution.
