反射创建实例

[丰常青]

//抽象类
public abstract Class AbstractClass{

public void init(){
}
}

//继承上面那个抽象类
public CostView extends AbstractClass{
public void init(){
}
}

//现在我想通过反射创建一个CostView 对象 赋值给 AbstractClass
// AbstractClass ss = 通过反射创建的CostView 对象；

[humanity]

String className = "CostView";

Class clazz = Class.forName(className);

AbstractClass instance = (AbstractClass) clazz.newInstance();

instance.init();

// ... ready to go.

恩，顶个~

[ditouye]

public class ReflectTest {

public static void main(String[] args) {
Class<?> cal = CostView.class;
AbstractClass t = null;
try {
t = (AbstractClass) cal.newInstance();
} catch (InstantiationException e) {
e.printStackTrace();
} catch (IllegalAccessException e) {
e.printStackTrace();
}
t.init();
}

}
