Why you should care

[/vc_column_text][vc_column_text]Abstract classes can have public constructors, and this is required in some particular cases. But a public constructor means that the class can be instantiated directly while, by design, abstract classes are aimed to not be instantiable.[/vc_column_text][vc_empty_space][/vc_column_inner][/vc_row_inner][vc_empty_space height=”12px”][vc_empty_space][vc_separator][vc_column_text]

How we detect

[/vc_column_text][vc_column_text]CAST Highlight counts one occurrence each time an abstract class is defining a public constructor.

abstract class MyClass {
def I = 0

public MyClass() { } // +1 VIOLATION

MyClass(int i) { // +1 VIOLATION (members are public by default)
I = i
}
}
