Shared coding conventions allow teams to collaborate efficiently. This rule checks that all constant names match a provided regular expression.
Noncompliant Code Example
With the default regular expression ^[A-Z][A-Z0-9]*(_[A-Z0-9]+)*$
:
public class MyClass { public static final int first = 1; } public enum MyEnum { first; }
Compliant Solution
public class MyClass { public static final int FIRST = 1; } public enum MyEnum { FIRST; }

Duplicated string literals make the process of refactoring error-prone, since you must be sure to update all occurrences.
On the other hand, constants can be referenced from many places, but only need to be updated in a single place.
Noncompliant Code Example
With the default threshold of 3:
public void run() { prepare("action1"); // Noncompliant - "action1" is duplicated 3 times execute("action1"); release("action1"); } @SuppressWarning("all") // Compliant - annotations are excluded private void method1() { /* ... */ } @SuppressWarning("all") private void method2() { /* ... */ } public String method3(String a) { System.out.println("'" + a + "'"); // Compliant - literal "'" has less than 5 characters and is excluded return ""; // Compliant - literal "" has less than 5 characters and is excluded }
Compliant Solution
private static final String ACTION_1 = "action1"; // Compliant public void run() { prepare(ACTION_1); // Compliant execute(ACTION_1); release(ACTION_1); }
Exceptions
To prevent generating some false-positives, literals having less than 5 characters are excluded.

The requirement for a final default
clause is defensive programming. The clause should either take appropriate action, or contain a
suitable comment as to why no action is taken.
Noncompliant Code Example
switch (param) { //missing default clause case 0: doSomething(); break; case 1: doSomethingElse(); break; } switch (param) { default: // default clause should be the last one error(); break; case 0: doSomething(); break; case 1: doSomethingElse(); break; }
Compliant Solution
switch (param) { case 0: doSomething(); break; case 1: doSomethingElse(); break; default: error(); break; }
Exceptions
If the switch
parameter is an Enum
and if all the constants of this enum are used in the case
statements,
then no default
clause is expected.
Example:
public enum Day { SUNDAY, MONDAY } ... switch(day) { case SUNDAY: doSomething(); break; case MONDAY: doSomethingElse(); break; }
