Is there a functionality in Java similar to C#'s anonymous types?

I was wondering if there exists a similar functionality in Java similar to C#'s anonymous types:

var a = new {Count = 5, Message = "A string."};

Or does this concept go against the Java paradigm?

EDIT:

I suppose using Hashable() in Java is somewhat similar.

Java has a feature called local classes, which are somewhat similar. They're useful for creating a class or implementing an interface that doesn't really need to be known about outside of a particular method. The scope of the local class is limited by the code block that defines it.

public void doSomething() {
    class SomeLocalClass {
        public int count = 5;
        public String message = "A string.";
    }

    SomeLocalClass local = new SomeLocalClass();
    System.out.println(local.count);
    System.out.println(local.message);
}

Unlike anonymous types in C#, Java local classes and their fields have explicitly defined types, but I imagine they might have some overlapping use cases.
