Define a constant instead of duplicating this literal "temperatureAlt" 4 times.

        assertEquals("tempAlt", nodeSettings.getString("temperatureAlt"));

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() {

Exceptions

To prevent generating some false-positives, literals having less than 5 characters are excluded.

Severity: Critical

There are several reasons for a method not to have a method body:

  • It is an unintentional omission, and should be fixed to prevent an unexpected behavior in production.
  • It is not yet, or never will be, supported. In this case an UnsupportedOperationException should be thrown.
  • The method is an intentionally-blank override. In this case a nested comment should explain the reason for the blank override.

Noncompliant Code Example

public void doSomething() {
}

public void doSomethingElse() {
}

Compliant Solution

@Override
public void doSomething() {
  // Do nothing because of X and Y.
}

@Override
public void doSomethingElse() {
  throw new UnsupportedOperationException();
}

Exceptions

Default (no-argument) constructors are ignored when there are other constructors in the class, as are empty methods in abstract classes.

public abstract class Animal {
  void speak() {  // default implementation ignored
