What Checkstyle Offers
The Checkstyle is capable of handling a wide range of things
starting from the coding conventions to the minute details of
javadoc. Because of this vastness, it is beyond the scope of
this article to discuss all of them. I shall try to cover some
important and mostly needed items from each section. The rest
can be referenced in the Checkstyle documentation.
Checks for Coding Problems
Several modules are defined in this domain. Some of them are:
AvoidInlineConditionals
This module checks for the use of inline conditions such as:
String s = (a ==null)? null:a;
If you do not like this sort of thing in your code, run a check for this module.
EqualsHashCode
This module ensures that whenever the equals() method is overridden for an
object, the hashCode() method is also overridden.
InnerAssignment
if you do not like variables to be assigned within logical operations such as
int I = Integer.parseInt(s = "1");
then run a check for this module.
Checks for Class Design
This module contains checks for different class design elements such as the
visibility of the class and its attributes.
VisibilityModifier
This module defines whether you are allowed to have a certain type of visibility
with its members. For example,
<module name=”VisibilityModifier”>
<property name=”protectedAllowed” value=”false”/>
</module>
This config does NOT allow the class to have protected members.
FinalClass
If a class does not have a public constructor, then in Java you cannot subclass
it. This module checks that such classes are declared final.
Checks for Imports
This module checks for redundant import statements, doing * imports.
AvoidStarImport
This module checks for .* style of imports.
UnusedImports
This checks for various things such as:
- Unused import statements
- Duplicate import statements
- imports from the same package
