    So it says that: classifier ExeptionClass does not have a companion object, and thus must be initialized here. So you want to throw an exception. You thus want to use orElseThrow (), and not orElse (). So you need to pass a supplier (i.e. a lambda) that creates and returns an exception, by invoking its constructor

    static members in Java are modeled as ordinary members of a companion object in Scala. When using a companion object from Java code, the members will be defined in a companion class with a static modifier. This is called static forwarding. It occurs even if you haven’t defined a companion class yourself. More resources. Learn more about Companion objects in the Scala Book ←

    Scala Singleton and Companion Object Scala Singleton Object. Singleton object is an object which is declared by using object keyword instead by class. No object is required to call methods declared inside singleton object. In scala, there is no static concept. So scala creates a singleton object to provide entry point for your program execution
