No Java is not a Pure Object Oriented Language. For any language to be pure object oriented it must follow these 6 points strictly
1. It must have full support for Encapsulation and Abstraction
2. It must support Inheritance
3. It must support Polymorphism
4. All predefined types must be Objects
5. All user defined types must be Objects
6. Lastly, all operations performed on objects must be only through methods exposed at the objects.

Java supports 1, 2, 3 & 5 but fails to support 4 & 6.

Now coming to second part of your query -

We need at least one class to have a complete program, because in Java, all code is inside classe. However, code doesn't necessarily need to be in a method. It can also be in initializers. See the following code -

class LookMaNoMethods {
    static {
        System.out.println("Hello, world!");
        System.exit(0);
    }
}
