You can use the .count() method to count the number of occurrences of a character in a string. For example, to count the number of occurrences of the letter "a" in the string "banana", you would use the following code: string = "banana" count = string.count("a") print(count) ...
String str = "hello"; char c = 'l'; int count = countChar(str, c); This will set count to 2, because there are two occurrences of 'l' in "hello". Alternatively, you could use the String.replace() method to remove all occurrences of the specified character from the st...

Handling character counts within a string is common in various programming scenarios. One efficient approach is to utilize a HashMap to store the frequency of each character in the string. In this tutorial, we’ll explore how to create a HashMap containing the character count of a given string...
