Why Am I Getting a \'Uncompilable Source Code\' Exception in Java?

Uncompilable Source Code Exception in Java

The java.lang.RuntimeException: Uncompilable source code exception can occur when an unexpected issue arises during code compilation. Despite apparent correctness, the error message can be perplexing, leaving developers perplexed.

Causes of the Exception

While the specific cause may vary, one common culprit is the "Compile on save" setting in NetBeans IDE. When enabled, this setting initiates compilation whenever the code changes. However, this feature can lead to compilation errors even when the code is syntactically valid.

Resolving the Issue

To resolve this issue, disable the "Compile on save" setting in the project properties. Navigate to Build > Compiling and uncheck the option.

Additional Considerations

• Double-check the code for any unrecognized characters or special symbols that may have crept in.
• If the error persists, restart NetBeans IDE completely.
• In some cases, a corrupted IDE installation can cause compilation issues. Consider reinstalling NetBeans to rule out this possibility.
