Overriding the ``++Object.finalize()++`` method must be done with caution to dispose some system resources.
|
|
|
|
Calling the ``++super.finalize()++`` at the end of this method implementation is highly recommended in case parent implementations must also dispose some system resources.

|
== Noncompliant Code Example
|
|
|
|
----
|
|
protected void finalize() { // Noncompliant; no call to super.finalize();
|
|
releaseSomeResources();
|
|
}
|
|
|
|
protected void finalize() {
|
|
super.finalize(); // Noncompliant; this call should come last
|
|
releaseSomeResources();
|
|
}
|
|

== Compliant Solution
|
|
|
|
----
|
|
protected void finalize() {
|
|
releaseSomeResources();
|
|
super.finalize();
|

}
