What are the different levels of abstraction?

Which class has highest level of abstraction?
Explanation: Phone as a whole have the highest level of abstraction.
What does level of abstraction mean?
The amount of complexity by which a system is viewed or programmed. The higher the level, the less detail. The lower the level, the more detail. The highest level of abstraction is the entire system. The next level would be a handful of components, and so on, while the lowest level could be millions of objects.
What is high level English?

What is the result of more abstraction?
Data abstraction allows us to transform a complex data structure into one that’s simple and easy to use. The effect of this is that a program with a high level of code complexity can be transformed into one that looks close to English (let’s call it high-level code). … The public ones are the only way to use the data.
What is a method in OOPs?
A method in object-oriented programming (OOP) is a procedure associated with a message and an object. … This allows the sending objects to invoke behaviors and to delegate the implementation of those behaviors to the receiving object. A method in Java programming sets the behavior of a class object.

High Level skips a lot of details, but gives a broad overview of the project focusing on goals, plans, and outcomes. If you include too much detail on how you plan to accomplish different parts of it, the expression for that is, “in the weeds”.
What is the role of abstraction?
Through the process of abstraction, a programmer hides all but the relevant data about an object in order to reduce complexity and increase efficiency. In the same way that abstraction sometimes works in art, the object that remains is a representation of the original, with unwanted detail omitted.
What is a high level goal?
High-level, long-term goals are derived from the key success factors. Goals are broad, directional, and fundamental to the mission and, as such, they may remain the same year after year.
How will a class protect the code inside it?
