Java - Use primitive data types as per requirement. For ex. for any number - don't use integer for age, student id, etc. If input format is known, use most suitable data type to store & process information. Create & reuse functions. TreeMap for automatic sorting of inserted elements.

Question

Accepted Answer

Use appropriate primitive data types in Java based on input format. Create and reuse functions, utilize TreeMap for automatic sorting.

Use byte for age if age is between 0-127, short for student id, int for large numbers like marks, long for very large numbers like phone numbers
Create functions for common tasks like input validation, data processing, etc. and reuse them throughout the code
Utilize TreeMap to automatically sort elements based on their natural ordering or a custom comparator
