Let's write one more program which counts total number of occurrence of a given character inside a given string. The program shows two different approaches to count the total occurrence. class CharacterCount { public static void main(String[] args) { String str = "Java is easy to learn"; char c = 'a'; int count = 0; // First Approach char[] charArray = str.toCharArray(); for(char ch : charArray) { if(ch == c) count++; } System.out.println("Total occurrence of character 'a' using 1st approach = "+count); // Second Approach int count2 = str.length() - str.replace("a", "").length(); System.out.println("Total occurrence of character 'a' using 2nd approach = "+count2); } }

Like other programming languages, Java allows you to collect and manage multiple values through an array object. Also, you manage data comprised of multiple characters through a String object.

May 24, 2022 - It is highly used by programmers due to its efficient and productive nature. A Java String Array is an object that holds a fixed number of String values. In this tutorial, let us dig a bit deeper and understand the concept of String array in Java.
