In this tutorial, we will see simple program to find frequency of characters in a string in java. There are multiple ways to solve this proble. Let’s see one by one. Table of Contents [hide] Using counter array

Scan the entire string and for each string element check the letter and increase the frequency in array by using ASCII value. (array[str[i]-'a']++)Like in str="aaabbccccddef",str [3] ='b'Thus, and str [2]-'a'=1Thus it increases the frequency of 'b' by 1 (array [str [3...
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....
