Since Checkstyle 3.1
Checks the style of array type definitions. Some like Java style:
public static void main(String[] args)
and some like
C style: public static void main(String args[])
.
By default, the Check enforces Java style.
This check strictly enforces only Java style for method return types
regardless of the value for 'javaStyle'. For example, byte[] getData()
.
This is because C doesn't compile methods with array declarations on the name.
name | description | type | default value | since |
---|---|---|---|---|
javaStyle | Control whether to enforce Java style (true) or C style (false). | boolean | true |
3.1 |
To configure the check to enforce Java style:
<module name="Checker"> <module name="TreeWalker"> <module name="ArrayTypeStyle"/> </module> </module>
Example:
public class MyClass { int[] nums; // OK String strings[]; // violation char[] toCharArray() { // OK return null; } byte getData()[] { // violation return null; } }
To configure the check to enforce C style:
<module name="Checker"> <module name="TreeWalker"> <module name="ArrayTypeStyle"> <property name="javaStyle" value="false"/> </module> </module> </module>
Example:
public class MyClass { int[] nums; // violation String strings[]; // OK char[] toCharArray() { // OK return null; } byte getData()[] { // violation return null; } }
All messages can be customized if the default message doesn't suit you. Please see the documentation to learn how to.
