java 内部抽象类如何创建

public class Test {
public abstract class Inner{
abstract void fun();
}

public static void main(String[] args) {
Test.Inner obj = null;//如何创建出来.请指教
}
}

public class Test {
public abstract class Inner{
abstract void fun();
}

public static void main(String[] args) {
Test test=new Test();
Test.Inner in=test.new Inner() {

@Override
void fun() {
// TODO Auto-generated method stub

}
};
in.fun();
}
}

package test; public abstract class MyTest0 { public abstract class MyTest1 { } } myTest1就是一个内部抽象类
