Reports non-final fields whose value never changes once object initialization ends, and hence may be marked final. Note that this rule does not enforce that the field value be deeply immutable itself. An object can still have mutable state, even if all its member fields are declared final. This is referred to as shallow immutability. For more information on mutability, see *Effective Java, 3rd Edition, Item 17: Minimize mutability*. Limitations: We can only check private fields for now. ImmutableField (Priority: 3, Ruleset: Design) https://docs.pmd-code.org/pmd-doc-7.9.0/pmd_rules_java_design.html#immutablefield

Switch statements should be exhaustive, to make their control flow easier to follow. This can be achieved by adding a `default` case, or, if the switch is on an enum type, by ensuring there is one switch branch for each enum constant. This rule doesn't consider Switch Statements, that use Pattern Matching, since for these the compiler already ensures that all cases are covered. The same is true for Switch Expressions, which are also not considered by this rule.

Detects when a local variable is declared and/or assigned, but not used. Variables whose name starts with `ignored` or `unused` are filtered out. UnusedLocalVariable (Priority: 3, Ruleset: Best Practices) https://docs.pmd-code.org/pmd-doc-7.9.0/pmd_rules_java_bestpractices.html#unusedlocalvariable

Java allows the use of several variables declaration of the same type on one line. However, it can lead to quite messy code. This rule looks for several declarations on the same line. OneDeclarationPerLine (Priority: 4, Ruleset: Best Practices) https://docs.pmd-code.org/pmd-doc-7.9.0/pmd_rules_java_bestpractices.html#onedeclarationperline

Reports fields which may be converted to a local variable. This is so because in every method where the field is used, it is assigned before it is first read. Hence, the value that the field had before the method call may not be observed, so it might as well not be stored in the enclosing object. Limitations: * We can only check private fields for now. * The rule is not aware of threading, so it may cause false positives in concurrent code. Such FPs are best handled by suppression (see also the `ignoredAnnotations` property). SingularField (Priority: 3, Ruleset: Design) https://docs.pmd-code.org/pmd-doc-7.9.0/pmd_rules_java_design.html#singularfield

Reports parameters of methods and constructors that are not referenced them in the method body. Parameters whose name starts with `ignored` or `unused` are filtered out. Removing unused formal parameters from public methods could cause a ripple effect through the code base. Hence, by default, this rule only considers private methods. To include non-private methods, set the `checkAll` property to `true`. UnusedFormalParameter (Priority: 3, Ruleset: Best Practices) https://docs.pmd-code.org/pmd-doc-7.9.0/pmd_rules_java_bestpractices.html#unusedformalparameter

Java will initialize fields with known default values so any explicit initialization of those same defaults is redundant and results in a larger class file (approximately three additional bytecode instructions per field).
