Noncompliant Code Example

This noncompliant code snippet uses a broad Exception class in the throws statement within the method declaration.

private void doSomething() throws Exception {
//...
}

Compliant Solution

To be compliant, be as specific as possible while declaring exceptions and heed the given abstraction level.

private void doSomething() throws IOException {
//...
}

Risk Assessment

Throwing RuntimeException, Exception, or General prevents classes from catching your exception without catching other unintended exceptions as well.
