简单的用反射实现工厂模式

public interface IFruit {
public void eat();

}

public class Apple implements IFruit{
@Override
public void eat() {
System.out.println("吃苹果");
}
}

public class Orange implements IFruit {
@Override
public void eat() {
System.out.println("吃橘子");
}
}

public class FruitFactory {

public static IFruit getFruit(String classname){
IFruit fruit = null;

try {
fruit = (IFruit) Class.forName(classname).newInstance();
} catch (InstantiationException e) {
e.printStackTrace();
} catch (IllegalAccessException e) {
e.printStackTrace();
} catch (ClassNotFoundException e) {
e.printStackTrace();
}
return fruit;
}
}

public class Test {
public static void main(String[] args) {
IFruit  fruit = FruitFactory.getFruit("com.wxw.ClassFactory.Apple");
fruit.eat();
}
}
