include::../description.adoc[]
|
|
|
|
=== Code examples
|
|
|
|
The following noncompliant code:
|
|
|
|
[source,java,diff-id=1,diff-type=noncompliant]
|
|
----
|
|
class MyClass {
|
|
public void doSomething() {
|
|
System.out.println("My Message"); // Noncompliant, output directly to System.out without a logger
|
|
}
|
|
}
|
|
----
|
|
|
|
Could be replaced by:
|
|
|
|
[source,java,diff-id=1,diff-type=compliant]
|
|
----
|
|
import java.util.logging.Logger;
|
|
|
|
class MyClass {
|
|
|
|
Logger logger = Logger.getLogger(getClass().getName());
|
|
|
|
public void doSomething() {
|
|
// ...
|
|
logger.info("My Message"); // Compliant, output via logger
|
|
// ...
|
|
}

|
}
