Final answer:
The task involves writing a Java program that takes two even-length numeronyms, processes them according to certain rules, and outputs a newly formed word using digits from the numeronyms with loops.
Step-by-step explanation:
The question asked involves writing a Java program. The program is supposed to take two numeronyms created by the user, process them according to specific rules, and then output a new sequence of characters forming a new word. The numeronyms must be greater than two digits, of equal length, and an even length each. The new sequence will use digits from the two numeronyms, by pairing last digits of the first halves in reverse order, separating them with an asterisk, and framing the sequence within square brackets.
The process requires understanding string manipulation without using arrays. Loops are utilized to iterate through the characters of the entered numeronyms from right to left, and string concatenation or a StringBuilder can be used to form the final word.
