Well-named functions can allow the users of your code to understand at a glance what to expect from the function - even before reading the documentation. Toward that end, methods returning a boolean should have names that start with "is" or "has" rather than with "get".

== Noncompliant Code Example

----
public boolean getFoo() { // Noncompliant
  // ...
}

public boolean getBar(Bar c) { // Noncompliant
  // ...
}

public boolean testForBar(Bar c) { // Compliant - The method does not start by 'get'.
  // ...
}
----

== Compliant Solution

----
public boolean isFoo() {
  // ...
}

public boolean hasBar(Bar c) {
  // ...
}

public boolean testForBar(Bar c) {
  // ...
}
----

== Exceptions

Overriding methods are excluded.

----
@Override
public boolean getFoo(){
  // ...
}
----
