Multiple inheritance in Java

1. Java subclasses inherit only one base class, but can implement multiple interfaces.

 Packagecom.test.wx; Public classTest {Interfacecanfight{voidfight (); }    Interfacecanswim{voidswim (); }    Interfacecanfly{voidFly (); }    classaction{ Public voidFight () {System.out.println ("Action"));} }    classHeroextendsActionImplementsCanfight,canswim,canfly {@Override Public voidFly () {//TODO auto-generated Method StubSystem.out.println ("Fly"); } @Override Public voidswim () {//TODO auto-generated Method StubSystem.out.println ("Swim"); }            }         Public Static voidt (canfight x) {x.fight ();}  Public Static voidu (canswim x) {x.swim ();}  Public Static voidV (canfly x) {x.fly ();}  Public Static voidW (Action x) {x.fight ();}  Public Static voidMain (string[] args) {Hero h=NewTest ().NewHero ();//the creation of an inner class object requires the use of the. Newt (h);        U (h);        V (h);            W (h); }}

2. Multiple inheritance of interfaces.

 Packagecom.test.wx; Public classTest {Interfacea{voidFA (); }    Interfaceb{voidFB (); }    InterfaceCextendsa,b{voidFC (); }        classDddImplementsc{@Override Public voidfa () {//TODO auto-generated Method Stub} @Override Public voidfb () {//TODO auto-generated Method Stub} @Override Public voidFC () {//TODO auto-generated Method Stub                    }            }}
