## Unused Code Rules

The Unused Code Ruleset contains a collection of rules that find unused code.

### UnusedPrivateField

Detects when a private field is declared and/or assigned a value, but not used.

This rule is defined by the following Java class: net.sourceforge.pmd.rules.UnusedPrivateFieldRule

Here's an example of code that would trigger this rule:

    public class Something {
      private static int FOO = 2; // Unused
      private int i = 5; // Unused
      private int j = 6;
      public int addOne() {
        return j++;
      }
    }

### UnusedLocalVariable

Detects when a local variable is declared and/or assigned, but not used.

This rule is defined by the following Java class: net.sourceforge.pmd.rules.UnusedLocalVariableRule

Here's an example of code that would trigger this rule:

    public class Foo {
     public void doSomething() {
      int i = 5; // Unused
     }
    }

### UnusedPrivateMethod

Unused Private Method detects when a private method is declared but is unused.

This rule is defined by the following Java class: net.sourceforge.pmd.rules.UnusedPrivateMethodRule

Here's an example of code that would trigger this rule:

    public class Something {
     private void foo() {} // unused
    }

### UnusedFormalParameter

Avoid passing parameters to methods or constructors and then not using those parameters.

This rule is defined by the following Java class: net.sourceforge.pmd.rules.UnusedFormalParameterRule

Here's an example of code that would trigger this rule:

    public class Foo {
     private void bar(String howdy) {
      // howdy is not used
     }
