Answer:
Digital electronics involves 2 states which are abstracted as 0/1 or true/false.
Explanation:
Digital electronics involves 2 states. For TTL logic this corresponds to 0 Volt (0) or 5 Volt (1). Analyzing further, a digital waveform has a square shape (not necessarily a perfect square) with 2 levels denoting the two states, namely, true(1) or false(0). So a 0 or 1 is not actually absolute but 0 corresponds to voltage level below a threshold voltage whereas 1 corresponds to voltage level above a threshold voltage.

Answer:
Following are the code to this question:
please find the attached file.
Explanation:
In this code, four class "novels, magazines, technical journals, and textbooks", is defined, in which it holds their respective default constructor and the get and set method to hold the string and integer value, and in the book class the main method is defined, that creates its object and a switch to for search value and print its value.
