There is a newer version: 8.6.0.37351

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.

Noncompliant Code Example
class ParentClass {
  public boolean doSomething(){...}
}
class FirstChildClass extends ParentClass {
  public boolean doSomething(){...}  // Noncompliant
}


Compliant Solution
class ParentClass {
  public boolean doSomething(){...}
}
class FirstChildClass extends ParentClass {
  @Override
  public boolean doSomething(){...}  // Compliant
}
