Use the adjective abstract for something that is not a material object or is general and not based on specific examples.
Abstract is from a Latin word meaning “pulled away, detached,” and the basic idea is of something detached from physical, or concrete, reality. It is frequently used of ideas, meaning that they don’t have a clear applicability to real life, and of art, meaning that it doesn’t pictorially represent reality. It is also used as a noun, especially in the phrase “in the abstract” (a joke has a person laying down a new sidewalk saying “I like little boys in the abstract, but not in the concrete”), and as a verb (accented on the second syllable), meaning “to remove.”
Or it can be said as a compliment; it just depends on how you take it.

The interface body can contain abstract methods, default methods, and static methods. An abstract method within an interface is followed by a semicolon, but no braces (an abstract method does not contain an implementation). Default methods are defined with the default modifier, and static methods with the static keyword. All abstract, default, and static methods in an interface are implicitly public , so you can omit the public modifier.
The public access specifier indicates that the interface can be used by any class in any package. If you do not specify that the interface is public, then your interface is accessible only to classes defined in the same package as the interface.
An abstract gives you key information about an article or other resource. It is like a summary but with more detailed and structured information. Abstracts vary in length but are very rarely more than a few paragraphs.
may also appear at the beginning of an article, before the introduction.
An abstraction is a general concept or idea, rather than something concrete or tangible. In computer science, abstraction has a similar definition. It is a simplified version of something technical, such as a function or an object in a program. The goal of “abstracting” data is to reduce complexity by removing unnecessary information.
At some level, we all think of computers in abstract terms. When we type a document in a word processor, we don’t think of the CPU processing each letter we type and the data being saved to memory. When we view a webpage, we don’t think of the binary data being transferred over the Internet and being processed and rendered by the web browser. We simply type our documents and browse the web. This is how we naturally abstract computing concepts.
