Answer 1

example of passing a lambda containing a method

YourClass myObject = new YourClass();

// first parameter, second parameter and return 
BiFunction YourFunction; 

YourFunction = (k, v) -> v == null ? "ERROR your class object is null" : defaultHandler("hello",myObject);

public String defaultHandler(String message, YourClass Object)
{
     //TODO ...

     return "";
}
