There are several reasons for a method not to have a method body:
|
|
|
|
|
|
* It is an unintentional omission, and should be fixed to prevent an unexpected behavior in production.
|
|
* It is not yet, or never will be, supported. In this case an ``++UnsupportedOperationException++`` should be thrown.
|
|
* The method is an intentionally-blank override. In this case a nested comment should explain the reason for the blank override.

== Noncompliant Code Example
|
|
|
|
----
|
|
public void doSomething() {
|
|
}
|
|
|
|
public void doSomethingElse() {
|
|
}
|

|
|
|
|
== Compliant Solution
|
|
|
|
----
|
|
@Override
|
|
public void doSomething() {
|
|
// Do nothing because of X and Y.
|
|
}
|
|
|
|
@Override
|
|
public void doSomethingElse() {
|
|
throw new UnsupportedOperationException();
|
|
}

== Exceptions
|
|
|
|
Default (no-argument) constructors are ignored when there are other constructors in the class, as are empty methods in abstract classes.
|
|
|
|
|
|
----
|
|
public abstract class Animal {
|
|
void speak() { // default implementation ignored
|
|
}
|
|
}
