Method names should always begin with a lower case character, and should not contain underscores. topscore - The Maximum Number of reports to generate. if the count is above the user defined threshold. For example, the code for creating specific objects needed in a method was moved from the method to the code for calling the method, but the created objects are passed to the method as parameters. Do not use protected fields in final classes since they cannot be subclassed.,,,, net.sourceforge.pmd.rules.CyclomaticComplexity, net.sourceforge.pmd.rules.ExcessivePublicCount, Newbie programmers sometimes get the comparison concepts confused Override both public boolean Object.equals(Object other), and public int Object.hashCode(), or override neither. This rule detects JUnit assertions in object equality. List of rulesets and rules contained in each ruleset. ), MoreThanOneLogger ( does nothing. Even if you are inheriting a hashCode() from a parent class, consider implementing hashCode and explicitly delegating to your superclass. The method name and parameter number are suspiciously close to This proabably means that type and or field names could be more precise. NOTE: In version 0.9 and higher, their are three parameters available: A field name is all in uppercase characters, which in sun's java naming sigma - Std Deviations away from the mean before reporting. ), AvoidNonConstructorMethodsWithClassName ( confusing and probably a bug to overload finalize(). ), WhileLoopsMustUseBraces ( problems with certain locales, i.e. ), SingularField ( Do not use "if" statements that are always true or always false. Avoid instantiating String objects; this is usually unnecessary. Code containing duplicate String literals can usually be improved by declaring the String as a constant field. a named break/continue label) was present in a switch statement. Avoid unnecessary return statements This prevents that future changes from the user affect the internal functionallity. Avoid calling toString() on String objects; this is unnecessary ), DefaultLabelNotLastInSwitchStmt ( ), DontImportJavaLang ( Reassigning values to parameters is a questionable practice. The Series table has to have enough numbers to cover the entire string, but unless you really like to type in long parameter list, this should not be a problem. ), UseNotifyAllInsteadOfNotify ( Type is boolean.Default value is false. ), DontImportSun ( Classes or interfaces nested in an interface are automatically public It is somewhat confusing to have a field name matching the declaring class name. 1-4 (low complexity) 5-7 (moderate complexity) 8-10 (high complexity) 10+ (very high complexity) 535–770: The method encodeTableBody() has an NPath complexity of 2133307936: 535–770: The method 'encodeTableBody' has a Cyclomatic Complexity of 53. ), SuspiciousConstantFieldName ( Detects when classes or interfaces are declared with excessively long names. Basically, try to group the parameters together. Scale: Some for loops can be simplified to while loops - this makes them more concise. many fields. Exception, or Error, use a subclassed exception or error instead. 535–539: The method 'encodeTableBody' has a Standard Cyclomatic Complexity of 46. Final variables should be all caps ), LocalVariableCouldBeFinal ( Avoid importing anything from the package 'java.lang'. ), AccessorClassGeneration ( ), UnusedLocalVariable ( PMD static analysis for Apex in vscode. Most "if (x != y)" cases without an "else" are often return Try to break it down, and reduce the size to something manageable. ), EmptyFinallyBlock ( ), SimplifyConditional ( Hence, by … Marking variables There is usually quite a bit of Cut and Paste there and some nested object grouping some of the information collected on the should be made by more specific methods, like assertEquals. too much. Object clone() should be implemented with super.clone() This rule is defined by the following Java class: method. These are confusing because most people will assume that the virtual machine threw it. This rule is defined by the following Java class: net.sourceforge.pmd.rules.AvoidReassigningParameters. Since: PMD 0.8. will not report it. A high ratio of statements to labels in a switch statement implies that the switch ), AvoidCallingFinalize ( assertEquals(), not the two argument version. Avoid idempotent operations - they are silly. ), SystemPrintln ( 534–767: Avoid long parameter lists. Basically, try to group the parameters together. Long parameter lists may also be the byproduct of efforts to make classes more independent of each other. Avoid empty finally blocks - these can be deleted. In most circumstances, this swallows an exception i <=LEN( @ inputString)+2 and n2. "I'm looking at some code, and I think I can write it nicer. Classes that have too many fields could be redesigned to have less fields Avoid empty catch blocks. Rule counts unique attributes, local variables and return types within an object. e.g. completely understand what is going on in the code. It is somewhat confusing to have a field name with the same name as a method. method entry. To avoid a method being called with a null parameter, you may consider using an IllegalArgumentException instead, making it clearly seen as a programmer-initiated exception. ), EmptyFinalizer ( I think PMD could define the structure and violations can definitely be grouped . ), CloneThrowsCloneNotSupportedException ( getting too long. Clarify your intent by using private or package access modifiers instead. ), UnnecessaryConversionTemporary ( Detects when a field, local or parameter has a short name. ), UnusedImports ( A method argument that is never assigned can be declared final. ), AvoidDeeplyNestedIfStmts ( The default label in a switch statement should be the last label, by convention. as the sole body of a for loop or while loop is probably a bug. Priority: High (1) Avoid throwing NullPointerExceptions manually. Finds usages of += for appending strings. Default value is 2.5 sigma greater than the mean. topscore - The Maximum Number of reports to generate. Unnecessary constructor detects when a constructor is not necessary; i.e., when there's only one constructor, String: 3.7: File that lists classes and rules to be excluded from failures. Default value is 2.5 sigma greater than the mean. This includes rules from SOLID and object calisthenics. ), NonStaticInitializer ( If that's what you're using ), SuspiciousHashcodeMethodName ( ArrayList is a much better Collection implementation than Vector. finalize() is called by the garbage collector on an object when garbage collection determines remember to add a private constructor to prevent instantiation. Code Size Rules: The Code Size Ruleset contains a collection of rules that find code size related problems. A large amount of public methods and attributes declared in an object can indicate the class may need equals(Object), which may mean you are trying (and failing) to override the equals(Object) ExcessiveClassLength: Long Class files are indications that the class may be trying to do too much.
