 In this post, we are going to write a java program to obtain the sum of first and last digit of four digit number in four different ways. 1. Java program to Obtain the sum of first and last digit using Scanner class: Program: import java.util.*; import java.io.*; class FirstLast { public static void main(String … Read more
