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
}
}

Checks for long lines.
Rationale: Long lines are hard to read in printouts or if developershave limited screen space for the source code, e.g. if the IDEdisplays additional information like project tree, class hierarchy,etc.
