Hello guys, if you are looking for a Java program to print the word and their count from a given file then you have come to the right place. Earlier, I have shared 100+ Data Strucutre and Algorithms Problems from interviews and in this article, I will show you how to find worlds and their count from a given file in Java. How to find the word and their count from a text file is another frequently asked coding question from Java interviews. The logic to solve this problem is similar to what we have seen in how to find duplicate words in a String, where we iterate through string and store word and their count on a hash table and increment them whenever we encounter the same word.
Top 5 Scala and Functional Programming Books & Online Courses in 2021 [Best of Lot]
Hello guys, if you are a Java developer who is interested in learning Scala or someone starting with Scala afresh and looking for some awesome Scala resources like books, courses, and tutorials then you have come to the right place. In the past, I have shared some free Scala courses to start with and today, I will share some of the best books to learn Scala and Functional Programming, particularly Java developers. While in this age of online courses, fewer and fewer people are using books to learn a new technology or skill but in my opinion, both books and courses have different purposes. I have taken many online courses and read even more books so I can tell that books are almost always more in-depth and provide comprehensive coverage than courses.
How to Print Floyd's Triangle in Java - Example Tutorial
Hello guys, In the last article, I have taught you how to print Pascal's triangle and in today's article, I'll teach you how to print Floyd's triangle in the Java program. Floyd's triangle is easier to print than Pascal's triangle because you don't need to take care of formatting the numbers as Floyd's triangle is a right-angle triangle. It is named after American computer scientist Robert Floyd, who has also contributed Floyd–Warshall algorithm, which efficiently finds all shortest paths in a graph, and Floyd's cycle-finding algorithm for detecting cycles in a sequence.
