IN JAVA Write a function that takes in user input as a string. For all characters which are numeric, double its value and, if it is two digits, then replace it with the sum of its digits (e.g., 6 → 12 → 3 whereas 3 → 6). For all characters which are in uppercase, replace it with lowercase. For all characters which are in lowercase, replace it with uppercase (e.g., m → M and N → n).  The program should keep asking the user to enter strings until they either enter ‘q’ or ‘Q’.

1. Implement function postal() that takes 6 inputs: a first name (as a string) a last name (as a string) an address (as a string) a city (as a string) a state (as a string) a zip code (as an integer)and then prints a mailing address in 3 lines as shown below.>>> postal('Ljubomir', 'Perkovic', '243 S Wabash Ave','Chicago', 'IL', 60304)Ljubomir Perkovic243 S Wabash AveChicago, IL 60304

Write a function biggestBuried(s), which the parameter s is a string, and the function returns the largest integer buried in the string. If there is no integer inside the string, then return 0. For example, biggestBuried('abcd51kkk3kk19ghi') would return 51, and biggestBuried('kkk32abce@@-33bb14zzz') would return 33, since the '-' character is treated like any other non digit. Note that a character is a digit if it is greater than or equal to '0' and less than or equal to '9'. Alternatively, you can use string.isdigit() to check if the string is a digit. Use the function in a program to test that it works properly by saying print(biggestBuried('abcd51kkk3kk19ghi')) answer should be 51 print(biggestBuried('kkk32abce@@-33bb14zzz')) answer should be 33  print(biggestBuried('this15isast22ring-55')) answer should be 55

Write a python function called replacer()  that takes two strings as arguments.             Argument1: A sentence where you have to make the changes.             Argument2: A word with the values either “vowel” or “consonant”.Your function should replace the characters of the sentence with “V” or “C” depending on the 2nd argument. If the word is “vowel”, then replace all the vowels with “V”. If the word is “consonant”, then replace all the consonants with “C”.[You are not allowed to use the replace() function]Function call1:replacer("It is MAT110 final", "vowels")Sample Output1:Vt Vs MVT110 fVnVlFunction call2:replacer("It is CSE110 final", "consonants")Sample Output 02:IC iC CCE110 CiCaC
