+
+ An explicit call was made to a finalize method. Finalize methods are meant to be executed at most once (by the garbage collector). Calling it explicitly could result in the method being executed twice for that object (once by you, once by the garbage collector).
+

+
+
+
+
+
+ Classes that have too many fields could be redesigned to have less fields and some nested object grouping some of the information collected on the many fields.

+
+
+
+
+
+
+
+ A high number of imports can indicate a high degree of coupling within an object. Rule counts the number of unique imports and reports a violation if the count is above the user defined threshold.
+
+ 3
+
+
+
+
+
+ Exposing internal arrays directly allows the user to modify some code that could be critical. It is safer to return a copy of the array.
+
+ 3
+
+
+
+ Non-constructor methods should not have the same name as the enclosing class.
+
+ 3
+
+
+
+ It is a good practice to call super() in a constructor. If super() is not called but another constructor, such as an overloaded constructor, of the class is called, this rule will not report it.
+
+ 3
+
+
+
+
+

+
+ This is dangerous because if a java.lang.Error, for example OutOfMemmoryError, occurs then it will be caught. The container should handle java.lang.Error. If application code will catch them, try to log them (which will probably fail) and continue silently the situation will not be desirable.

+
+
+
+

+
+
+
+
+
+
+ Fields in interfaces are automatically public static final, and methods are public abstract. Classes or interfaces nested in an interface are automatically public and static (all nested interfaces are automatically static). For historical reasons, modifiers which are implied by the context are accepted by the compiler, but are superfluous.
+
+ 3
+
+
+
+
+
+
+
+ Calling overridable methods during construction poses a risk of invoking methods on an incompletely constructed object. This situation can be difficult to discern. It may leave the sub-class unable to construct its superclass or forced to replicate the construction process completely within itself, losing the ability to call super(). If the default constructor contains a call to an overridable method, the subclass may be completely uninstantiable. Note that this includes method calls throughout the control flow graph - i.e., if a constructor Foo() calls a private method bar() that calls a public method buz(), there's a problem.
+
+ 1
+
+
+
+ The abstract class does not contain any abstract methods. An abstract class suggests an incomplete implementation, which is to be completed by subclasses implementing the abstract methods. If the class is intended to be used as a base class only (not to be instantiated direcly) a protected constructor can be provided prevent direct instantiation.
+
+ 3
+
+
+
+
+
+
+
+ A nonstatic initializer block will be called any time a constructor is invoked (just prior to invoking the constructor). While this is a valid language construct, it is rarely used and is confusing.

+
+
+ At some places Exception is caught and then a check with instanceof is performed. This result in messy code. It's considered better to catch all the specific exceptions instead.

+ Complexity is determined by the number of decision points in a method plus one for the method entry. The decision points are 'if', 'while', 'for', and 'case labels'. Scale: 1-4 (low complexity) 5-7 (moderate complexity) 8-10 (high complexity) 10+ (very high complexity)

+ It is somewhat confusing to have a field name with the same name as a method. While this is totally legal, having information (field) and actions (method) is not clear naming.

+
+ Instantiation by way of private constructors from outside of the constructor's class often causes the generation of an accessor. A factory method, or non-privitization of the constructor can eliminate this situation. The generated class file is actually an interface. It gives the accessing class the ability to invoke a new hidden package scope constructor that takes the interface as a supplementary parameter. This turns a private constructor effectively into one with package scope, though not visible to the naked eye.

Try to reduce the method size by creating helper methods, and removing cut and paste. Default value is 2.5 sigma greater than the mean. There are three parameters available: minimum - Minimum Length before reporting. sigma - Std Deviations away from the mean before reporting. topscore - The Maximum Number of reports to generate.

For example, rephrase: if (x != y) diff(); else same(); as: if (x == y) same(); else diff(); Most "if (x != y)" cases without an "else" are often return cases, so consistent use of this rule makes the code easier to read.
