Saurabh Dixit created ROL-2159:
----------------------------------
Summary: "@Override" should be used on overriding and implementing
methods
Key: ROL-2159
URL: https://issues.apache.org/jira/browse/ROL-2159
Project: Apache Roller
Issue Type: Improvement
Affects Versions: 6.0.0
Reporter: Saurabh Dixit
Assignee: Saurabh Dixit
Using the {{@Override}} annotation is useful for two reasons :
* It elicits a warning from the compiler if the annotated method doesn't
actually override anything, as in the case of a misspelling.
* It improves the readability of the source code by making it obvious that
methods are overridden.
h2. Noncompliant Code Example
{code:java}
class ParentClass {
public boolean doSomething(){...}
}
class FirstChildClass extends ParentClass {
public boolean doSomething(){...} // Noncompliant
}{code}
h2. Compliant Solution
{code:java}
class ParentClass {
public boolean doSomething(){...}
}
class FirstChildClass extends ParentClass {
@Override
public boolean doSomething(){...} // Compliant
}{code}
h2. Exceptions
This rule is relaxed when overriding a method from the {{Object}} class like
{{toString()}}, {{hashCode()}}, ...
