For memory usage you can use following command:

long total = Runtime.getRuntime().totalMemory();

Write a Java program to find the Sum of last digits of two given numbers?

Rohit wants to add the last digits of two given numbers.
For example, If the given numbers are 267 and 154, the output should be 11.

Below is the explanation -
Last digit of the 267 is 7
Last digit of the 154 is 4
Sum of 7 and 4 = 11

Write a program to help Rohit achieve this for any given two numbers.

Note: The sign of the input numbers should be ignored. i.e.
if the input numbers are 267 and 154, the sum of last two digits should be 11
if the input numbers are 267 and -154, the sum of last two digits should be 11
if the input numbers are -267 and 154, the sum of last two digits should be 11
if the input numbers are -267 and -154, the sum of last two digits should be 11
