Write a function in the Java programming language that will take a string that has mixed characters and numbers in it$.$Your task is to find all the numbers in the string and add them up$,$returning the sum of the numbers extracted from the string. Some helpful functions are the Character.isDigit$($char$)$which will return true if the parameter character is a digit $0-9,$and Integer.parseInt$($string$)$that will convert a string to an integer equivalent. No negative numbers will appear in the input string.

For example

findAndAdd$("$xyz$432$abc"$)$should return $432.$

findAndAdd$("$xyz$432$abc$444")$should return $876.$

findAndAdd$("123")$should return $123.$

findAndAdd$("11235")$should return $12.$

findAndAdd$("$abcxyz$")$should return $0.$

Start of Code:

public class Finder $\{$

public static int findAndAdd$($String s$)\{$

int result $=-1$;
