+ With Delphi interface I mean the following:
+ 
+ unit test;
+ 
+ interface { stuff that could be seen from out of unit test. }
+ 
+   function test01( a: integer ): integer;
+ 
+ implementation { this stuff is only visible within the unit test. }
+ 
+   function test01( a: integer ): integer;
+   begin
+     result := a + 1;
+   end;
+ 
+ end.
+ 
+ With Java interfaces I mean the possibility to define totally abstract
+ classes (only method headers, no implementation), that could 
+ be used for
+ multiple inheritence. A (real) Java-class could have only one 
+ superclass,
+ but none or more interfaces. Clear?

Like Delphi ??

type
  IMyInterface = interface
    procedure P1;
    procedure P2;
  end;
