Overly generic exceptions should not be thrown JAVA-W1042


throws clauses should not contain generic exception types such as Throwable, Exception, or RuntimeException.

Instead, extend RuntimeException and create more specific exception types which are relevant to your use case.

This issue will be reported for method and constructor declarations with throws clauses that contain any of the following exception types:

  • java.lang.Throwable
  • java.lang.Exception
  • java.lang.RuntimeException

Bad Practice

Avoid using overly generic exception types:

public float getPercent() throws RuntimeException { ... }


Use a more specific exception type instead.

class CalculationException extends RuntimeException {
    // ...

// ...

public float getPercent() throws CalculationException { ... }
