In this article, we will learn how we can use multithreading in Ruby. We will take a couple of examples, where we will spawn two new threads and then perform some concurrent operations on them. In Ruby, we can create a new thread with the help of the Thread.new() function.Example 1Take a look at the following example to understand the nature of multiple threads and how they are executed in Ruby.#!/usr/bin/ruby # first method def First_Method    a = 0    while a

Ruby's integer class is the foundation for the two concrete classes that represent whole numbers. Bignum and Fixnum are these concrete classes. Bignum holds the integer value that is outside the range of Fixnum, which is displayed in the native machine word.There are a variety of methods in the integer class that can be used to perform various tasks. Numeric class has a subclass called Integer. Let's check some of the useful methods that are available in the integer class in Ruby.to_i methodThe to_i method is used to return an integer. Consider the code shown belowExampleConsider the code shown below.num ... Read More

In Ruby, there are four different types of variables that we can declare −Local VariablesInstance VariablesClass VariablesGlobal VariablesAn Instance variable has a name that starts with the @ symbol. It should be noted that the contents of an instance variable are only restricted to the object which itself refers to.An important point to note about the instance variable in Ruby is that, even if we have two separate objects that belong to the same class, we are allowed to have different values for their instance variables.Instance Variable Characteristics in RubyBefore checking how to use instance variables in Ruby, let's understand ...

In Ruby, when we are using the include keyword, we are importing a module code, but we aren't allowed to access the methods of the imported modules with the class directly because it basically gets imported as a subclass for the superclass.On the other hand, when we are using the extend keyword in Ruby, we are importing the module code but the methods are imported as class methods. If we try to access the methods that we imported with the instance of the class, the compiler will throw an error.Now let's use these two keywords in a Ruby code to ... Read More

In Ruby, we use the "or" keyword to return the logical difference between its two operands. In simple terms, we can say that a condition becomes True if both the operands are true."or" returns True if any one of the conditions/expressions is "true".It returns False only when all the conditions are "false".It should be noted that the or keyword is equivalent to the "||" logical operator, but it has lower precedence in Ruby.SyntaxThe syntax of the or keyword is shown below.Condition1 or Condition2Let's use the or keyword in a Ruby code and see how it works.Example 1Consider the code shown ...
