Message: <blockquote data-quote="sihina_lahiru" data-source="post: 7285046" data-attributes="member: 149577">2.Defining an Interface                An interface declaration consists of modifiers, the keyword interface,   the interface name, a comma-separated list of parent interfaces (if  any), and the interface body. For example: public interface GroupedInterface extends Interface1,                                         Interface2, Interface3 {    // constant declarations    double E = 2.718282;  // base of natural logarithms    // method signatures    void doSomething (int i, double x);    int doSomethingElse(String s); }   The public access specifier indicates that the interface  can be used by any  class in any package. If you do not specify that the interface  is public, your interface will be accessible only to classes defined in the same package as the interface.   An interface can extend other interfaces,  just as a class can extend or subclass another class. However,  whereas a class can extend only one other class, an interface  can extend any number of interfaces. The interface declaration includes  a comma-separated list of all the interfaces that it extends.   The Interface Body   The interface body contains method declarations for all the  methods included in the interface. A method declaration within  an interface is followed by a semicolon, but no braces, because  an interface does not provide implementations for the methods  declared within it. All methods declared in an interface are implicitly  public, so the public modifier can be omitted.   An interface can contain constant declarations in addition to  method declarations. All constant values defined in an interface  are implicitly public, static, and final.  Once again, these  modifiers can be omitted.          </blockquote>
