To compare two strings in C++, we can use various inbuilt functions and approaches that are already discussed in the previous sections. However, there are some cases where we need to compare two strings case-insensitively, meaning that we need to ignore the case of the characters in the strings while comparing them. In this article, we will focus on learning how to compare two strings case-insensitively in C++. Here is a list of approaches for case-insensitively string comparison, which we will be discussing in this article with stepwise explanation and complete example codes. ... Read More
Complex numbers is the combination of both real and imaginary components. Sometimes they are written as a + bi, where - a is the real part or number, b is the imaginary part, i is the imaginary unit which is basically a square root of -1. The imaginary part is written as the letter i. It is basically a square root of -1. Python already has support for complex numbers so it is easy to use them. So in this article, we will explain the basic ideas of complex numbers in Python, like how to create them, ... Read More
In Python, a list is an ordered sequence that can hold several object types, such as integers, characters, or floats. In other programming languages, a list is equivalent to an array. Square brackets [] are used to denote it, and a comma (, ) is used to divide two items in the list. In this article, we will show you how to get a comma-separated string from a list using Python. Comma-Separated String using join() ... Read More
A list is a data structure in Python that is a mutable or changeable ordered sequence of elements. A list's items are any elements or values that are contained within it. Lists are defined by having values inside square brackets [], just as strings are defined by characters inside quotations. They are used to store multiple items in a single variable. In Python, strings are among the most widely used types. We can create them simply by enclosing characters in quotes. Python treats single quotes the same as double quotes. Creating strings is as simple as assigning a value to ... Read More
Sometimes it is necessary to divide a lengthy list into smaller and easy-to-read data. For example- if you wish to arrange a list of items in groups, it can be helpful to break it into small parts. This is useful for tasks like grouping data for analysis or showing items in a user interface. Python provides various simple methods to do this. In order to work with smaller data sets without losing any information, this article will show you how to split a list into uniformly sized chunks. What is List? List is one of the frequently used data ... Read More
Iterator and Enumeration are both cursors to traverse and access elements from the collection. They both belong to the collection framework. Enumeration was added in JDK1.0 and Iterator in JDK 1.2 version in the collection framework. Java Enumeration Enumeration: An enumeration is a special "class" that indicates a collection of constants. Enumeration can’t make structural changes in the collection because it has read-only access to its elements. It has the following methods − hasMoreElements(): The hasMoreElements() method checks to see if more elements exist in the underlying collection class nextElement(): The ... Read More
Save and SaveAndFlush both can be used for saving entities. They both are both belong to the Spring data library. Save may or may not write your changes to the DB straight away. When we call saveAndFlush system is enforcing the synchronization of your model state with the DB. What is the save method? The save method is used to store an entity in the database. It adds the entity to the transactional buffer, and when the transaction is committed, the data is saved. It then returns the stored entity. Example The following is an example of the save method ...

In this article, we will find the differences between Fail-Fast and Fail-Safe Iterators. They both describe how collections behave when they are modified during iteration. What is an iterator? An Iterator is an object in Java used to cycle through a collection, accessing or removing elements. It can be obtained by using the iterator() method of a collection. What is FailSafe? Fail-safe also called a Non-Fail-fast Iterator, does not throw ConcurrentModificationException. It works on a copy of the collection. Any changes made in the iterator only affect the copy but not the original collection. Example The following is an ... Read More
As you may know a string is a group of letters, numbers, or symbols in Python. Sometimes we do not need the whole string. We may only want a small part of it. For example, we may want only the first 100 characters. Python makes this easy by using something called slicing. Slicing means taking a part of the string. We use square brackets [] with numbers inside to do this. It is a very useful and simple way to get the part of a string that we need. In this article, we will show you how to get ... Read More
In this article, we will find the differences between volatile and Transient. Both have a different purpose for specifying before a variable. These modifiers are important in determining the behavior and characteristics of variables in different cases. What is volatile? A volatile keyword is used in a multithreading environment where two threads reading and writing the same variable simultaneously. The volatile keyword flushes the changes directly to the main memory instead of the CPU cache. Example of Volatile The following is an example of Volatile in Java: public class VolatileExmaple extends Thread { volatile boolean isRunning ... Read More
