9,085 PointsStruggling with Putting it all together challenge task 4 of 4 in java Annotation course
First 3 tasks i completed, and i attempted the 4th task but am a little lost on what to do.
My attempt is what i saw during the course videos and what i had on the course workspaces.
Task goal In the TestAnalyzer class, implement (complete) the getNumAnnotatedMethods method. The details of how it should function are given in the comment above the method.
output.html error messages
./TestAnalyzer.java:8: error: cannot find symbol
int annotatedMethodCount = clazz.methods().length;
^
symbol: method methods()
location: variable clazz of type Class
./TestAnalyzer.java:9: error: cannot find symbol
int actualMethodCount = clazz.getMethodCount();
^
symbol: method getMethodCount()
location: variable clazz of type Class

19,589 PointsI think that you are making things a little complex.
The way that I solved the problem was to initialize an integer with a value of 0. Then I looped through the declared methods using
clazz.getDeclaredMethods. Then I checked to see if the method was annotated usingmethod.isAnnotationPresent(Test.class). If this was true, I just incremented the count and returned that at the end.Hopefully, that helps anybody going forward.
