    public interface Answer4<T,​A0,​A1,​A2,​A3>
    Generic interface to be used for configuring mock's answer for a four argument invocation. Answer specifies an action that is executed and a return value that is returned when you interact with the mock.

    Example of stubbing a mock with this custom answer: 

    
 import static org.mockito.AdditionalAnswers.answer;

 when(mock.someMethod(anyInt(), anyString(), anyChar(), any())).then(answer(
     new Answer4<StringBuilder, Integer, String, Character, Object>() {
         public StringBuilder answer(Integer i, String s, Character c, Object o) {
             return new StringBuilder().append(i).append(s).append(c).append(o.hashCode());
         }
 }));

 //Following will print a string like "3xyz131635550"
 System.out.println(mock.someMethod(3, "xy", 'z', new Object()));
