Question

and
String var2 = "123456abcdef"

should return 123456 and abcdef respectively

var1 and var 2 are user input

Answer 1

String var3 = var1.substring(var1.length() - 6, var1.length())

That should work.
Documentation is below.

Answer 2

You can use the java string class to read the string.length(), then use the length() - 6 to read the string from there. Remember the string will start at a count of 0, then go to length() - 1 as it is 0 indexed.

Answer 3

get the total length of the string
them move back to lenghtOfString-6 then start reading character by character from current posotion to the end of string.

Answer 4

i will give the logic

get the string and reverse it.and get the first 6 chars of that string then again reverse it.you will get the required answer.
