Looking at the set of methods in a class, including superclass methods, and finding two methods or fields that differ only by capitalization is confusing to users of the class. It is similarly confusing to have a method and a field which differ only in capitalization or a method and a field with exactly the same name and visibility.
In the case of methods, it may have been a mistake on the part of the original developer, who intended to override a superclass method, but instead added a new method with nearly the same name.
Otherwise, this situation simply indicates poor naming. Method names should be action-oriented, and thus contain a verb, which is unlikely in the case where both a method and a member have the same name (with or without capitalization differences). However, renaming a public method could be disruptive to callers. Therefore renaming the member is the recommended action.
Noncompliant Code Example
public class Car{ public DriveTrain drive; public void tearDown(){...} public void drive() {...} // Noncompliant; duplicates field name } public class MyCar extends Car{ public void teardown(){...} // Noncompliant; not an override. It it really what's intended? public void drivefast(){...} public void driveFast(){...} //Huh? }
Compliant Solution
public class Car{ private DriveTrain drive; public void tearDown(){...} public void drive() {...} // field visibility reduced } public class MyCar extends Car{ @Override public void tearDown(){...} public void drivefast(){...} public void driveReallyFast(){...} }

Duplicated string literals make the process of refactoring error-prone, since you must be sure to update all occurrences.
On the other hand, constants can be referenced from many places, but only need to be updated in a single place.
Noncompliant Code Example
With the default threshold of 3:
public void run() { prepare("action1"); // Noncompliant - "action1" is duplicated 3 times execute("action1"); release("action1"); } @SuppressWarning("all") // Compliant - annotations are excluded private void method1() { /* ... */ } @SuppressWarning("all") private void method2() { /* ... */ } public String method3(String a) { System.out.println("'" + a + "'"); // Compliant - literal "'" has less than 5 characters and is excluded return ""; // Compliant - literal "" has less than 5 characters and is excluded }
Compliant Solution
private static final String ACTION_1 = "action1"; // Compliant public void run() { prepare(ACTION_1); // Compliant execute(ACTION_1); release(ACTION_1); }
Exceptions
To prevent generating some false-positives, literals having less than 5 characters are excluded.
