Change the visibility of this constructor to "protected". Open
public SparkApp() {- Read upRead up
- Exclude checks
Abstract classes should not have public constructors. Constructors of abstract classes can only be called in constructors of their subclasses. So
there is no point in making them public. The protected modifier should be enough.
Noncompliant Code Example
public abstract class AbstractClass1 {
public AbstractClass1 () { // Noncompliant, has public modifier
// do something here
}
}
Compliant Solution
public abstract class AbstractClass2 {
protected AbstractClass2 () {
// do something here
}
}
Parameter name 's' must match pattern '^[a-z][a-z0-9][a-zA-Z0-9]*$'. Open

- Exclude checks
Checks that method parameter names conform to a specified pattern.By using accessModifiers property it is possibleto specify different formats for methods at different visibility levels.
To validate catch parameters please useCatchParameterName.
To validate lambda parameters please useLambdaParameterName.
