We can use HashMap as well to find Frequency of Each Character in a String. Create a HashMap which will contain character to count mapping. Iterate over String make count to 1 if HashMap do not contain the char
If it's a match, we increase the value of frequency by 1. In the end, we get the total occurence of a character stored in frequency and print it. Here's the equivalent Java code: Java program to find the frequency of a character in a string....

Sort Character by Frequency bucket sort For this problem, each frequency should be bounded in 0-len. (len is the length of the string). To achieve the O(n), use bucket sort. To put the same character together, use a arraylist for each bucket unit. import java.util.ArrayList; public ...
