Given an array, only rotation operation is allowed on array. We can rotate the array as many times as we want. Return the maximum possible summation of i*arr[i]....

In Java, Parallelism can be used to perform Matrix Multiplication using multiple threads concurrently. The major advantage of this technique is that it uses distributed computing environments to speed up the computation. In this article, we will learn how to perform Parallel Matrix Multiplication in Java....

It is common practice in Java to split strings into smaller strings of equal length to process larger strings into usable substrings. We can do this with the substring method of the loop. This method extracts a substring of the specified length from the input string and stores it in a list....

In Java, the Levenshtein Distance Algorithm is a pre-defined method used to measure the similarity between two strings and it can be used to calculate the minimum number of single-character edits (inserts, deletions, or substitutions) required to change one string into another....

The equals() method of the String class compares the content of two strings. It returns false if any of the characters are not matched. It returns true if all characters are matched in the Strings. It compares the value’s character by character, irrespective of whether two strings are stored in the same memory location. The String equals() method overrides the equals() method of the object class....

In Java, String Plays an important role. As String stores or we can say it is a collection of characters. We want to get a specific line from a multi-line String in Java. This can also be done in Java....

Working with strings is a typical activity in Java programming, and sometimes we need to remove duplicate characters from a string. Using hashing is one effective way to do this. By assigning a unique hash code to each element, hashing enables us to keep track of unique items. This article will examine the use of hashing in Java to eliminate duplicates from a string....

In Java programming, there are situations in which we must convert a string of numeric characters into one of the following data types: double, float, long, or int. To execute arithmetic operations and other numerical calculations, this conversion is necessary. We will look at how to convert a string to numeric types in Java in this tutorial....

We know that the Strings are a collection of characters so if we want to find the intersection of two Strings the simple way is we can compare each character of the first String with the characters of the Second String....

In this article, we will explain how to remove all punctuation from a given String by using Java with the help of Regex. Here regex means regular expression. The regex is a powerful way to explain the search pattern. One more thing is that regular expressions are mostly used for Searching a required pattern, and matching the pattern and the other one is Manipulating text based on the required pattern....

Regex is a very interesting way to search for patterns in a String that the user provides. Regex stands for Regular Expressions. It consists of some patterns that can be planned and modified according to the usage of the program....

Rearranging the order of characters, in a string can be done by shuffling them. Although the shuffle() method provided by Java’s Collections class is handy there are situations where you might require approaches. In this article, we will explore techniques, for shuffling characters in a string without using the shuffle() method....
