Public Class Public Static Void Int Int Double: / Created by Akshay On 11/9/2016.

The document contains code for several Java programs that use conditional statements like if-else and switch-case to evaluate user input. The programs include calculating student grades based on marks, performing arithmetic operations based on user selection, printing month names and number of days from user-selected month number, and more. All programs take input from the user, evaluate it using conditions, and print corresponding outputs.
