我建议
<div class="container" data-ng-class="{ 'yourcustomclass': pics.length > 0 }"></div>

这样做:
class AB {
public void dog() {
System.out.println("Dog");
}
}
class C extends AB {
public void cat() {
System.out.println("Cat");
}
}
class ABC {
public static void main(String[] args) {
AB obj1 = new AB();
C obj2 = new C();
AB obj3 = new C();
obj1.dog();
obj2.cat();
obj2.dog();
obj3.dog();
//obj3.cat();
}
}
