Java: Rearrange the alphabets in the order followed by the sum of digits
Java Basic: Exercise-192 with Solution
Write a Java program to rearrange the alphabets in the order followed by the sum of digits in a given string containing uppercase alphabets and integer digits (from 0 to 9).
Pictorial Presentation:

Sample Solution:
Java Code:
import java.util.*;
import java.lang.*;
public class Solution {
static final int MAX_CHAR = 20;
public static void main(String args[]) {
String str1 = "AND456HSE8";
System.out.println(arrange_String_nums(str1));
}
static String arrange_String_nums(String str1) {
int char_count[] = new int[MAX_CHAR];
int sum_num = 0;
for (int i = 0; i < str1.length(); i++) {
if (Character.isUpperCase(str1.charAt(i)))
char_count[str1.charAt(i) - 'A']++;
else
sum_num = sum_num + (str1.charAt(i) - '0');
}
String rarr_part = "";
for (int i = 0; i < MAX_CHAR; i++) {
char ch = (char)('A' + i);
while (char_count[i]-- != 0)
rarr_part = rarr_part + ch;
}
if (sum_num > 0)
rarr_part = rarr_part + sum_num;
return rarr_part;
}
}
Sample Output:
