Equivalent of C# ObservableCollection in Java

I was wondering if there is a data structure that acts like an OberservableCollection almost like in C# that is able to take a certain type. ex: In C# i am able to say.. ``` ObservableCollection<Beer> Beer = new ObservableCollection<Beer>(); Beer.add("Bud"); <br> Beer.add("Coors"); ``` Assuming that the class Beer is made and we can change the alcohol content so that ``` Beer[1].content = 5; ``` I was wondering if anyone knows if there is such a data structure/s that work as well with Java. I am a C# programmer, not much of a Java programmer so just wondering. Also, it has to be able to take in a custom type, not generic.
