This post will discuss how to find the total number of occurrences of one string in another string in Java. A null or a string input should return 0.
To find multiple occurrences of character in String: Use list comprehension to iterate over each character of given String with enumerate(). For each character, compare it with given character. If condition is met, return the index. Result will be list of the indices of character in the Strin...
Let us start with writing the program logic ourselves. In this solution, we are creatingMapwhere each unique character in the string is theMapkey, and the number of occurrences of the character is stored as the value. 1.1. Algorithm Split the string into a character array. Iterate over the...

In this Java tutorial, you will learn How to Find Maximum Occurrence of Words from given Text File? Here is a logic for getting top element: Create a class CrunchifyComparable that can store the String value of the word and the number of occurrences it appears. Implement the Comparable inte...
In this tutorial, we’ll demonstrate a simple algorithm that uses the indexOf(String str, int fromIndex) method of the Java String class to find all occurrences of a word within a string. 2. Simple Algorithm Instead of simply counting the occurrences of a word in a larger text,...
Java Program to find the Last Index of a Particular Word in a String - In Java, a string is also an object. It is the object of the String class. A String is a sequence of characters. The last index of a particular word in a string is nothing but the pos

Given an M× N matrix of characters, find all occurrences of a given string in the matrix. We are allowed to search the string in all eight possible directions, i.e., North, West, South, East, North-East, North-West, South-East, South-West. Note that there should not be any ...
Toretrieve the index of all the occurrences of a word in the string(say a statement), Python, like most of the programming languages supports theregular expression moduleas a built-in module. Or if we don't want the overhead of using the regular expressions, we could also use the...
