是否可以捕获方法的所有异常，但应引发的特定异常除外？

void myRoutine() throws SpecificException { 
    try {
        methodThrowingDifferentExceptions();
    } catch (SpecificException) {
        //can I throw this to the next level without eating it up in the last catch block?
    } catch (Exception e) {
        //default routine for all other exceptions
    }
}

void myRoutine() throws SpecificException { 
    try {
        methodThrowingDifferentExceptions();
    } catch (SpecificException se) {
        throw se;
    } catch (Exception e) {
        //default routine for all other exceptions
    }
}

你可以这样做

try {
    methodThrowingDifferentExceptions();    
} catch (Exception e) {
    if(e instanceof SpecificException){
      throw e;
    }
}
