Introduction PEMDAS means the order of operations for mathematical expressions involving more than one mathematical operations. In an arithmetic expression containing more than one mathematical operator or a parenthesis, there is a preference in order of operations to be followed to get the correct result of the arithmetic expression the order of operations in a shortcut called PEMDAS. The change in the order of operations would change the result of the arithmetic expression. Therefore, the PEMDAS rule is strictly followed to get the correct result. In the United Kingdom, it is called BODMAS, in Canada, it is called BEDMAS. In ... Read More
Introduction Pictographs are graphs used to represent data using symbols and images associated with the data. Pictographs are a way of expressing data using images. Each image of the icon represents a specific number. That is, the icon uses images and symbols to convey information about the data provided. Pictograms need to be used very carefully and are very convenient to use, but they can also misinterpret the data. When drawing a pictogram, the data is most often interpreted visually and should look visually correct. You can easily interpret your data using various image representations of your data, such as ... Read More
Introduction The polar form of a complex number $\mathrm{z\:=\:x\:+\:iy\:is\:r(\cos\theta\:+\:i\:\sin\theta)}$.In mathematics, there are various coordinate systems to represent real numbers. However, the complex number system can be represented in two ways, i.e., rectangular and polar coordinate systems. In this tutorial, we will learn about complex numbers, their representation in polar form, and some basic formulae related to complex numbers with solved examples. Complex Number The complex number is a category of a number system associated imaginary numbers. In other words, complex numbers are the summation of real and imaginary numbers. The imaginary numbers are nothing but the square root of the ... Read More
The Layout managers enable us to control the way in which visual components are arranged in the GUI forms by determining the size and position of components within the containers. Types of LayoutManager There are 6 layout managers in Java FlowLayout: It arranges the components in a container like the words on a page. It fills the top line from left to right and top to bottom. The components are arranged in the order as they are added i.e. first components appears at top left, if the container is not wide enough to display all the components, ... Read More
Introduction One to one functions that maps every element of the range to one element of its domain. Functions are defined as relationships between a set of inputs, each with an output. Simply put, a function is a relationship between inputs, where each input is associated with one output. Each function has a domain and a codomain or range. Functions are commonly represented by 𝑓 (𝑥), where x is the input. The general representation of a function is $$\mathrm{y\:=\:f(x)}$$ In a mathematical sense, these relationships can be described as one-to-one functions. In this case, the number of elements is the ... Read More
Introduction Odd Numbers and even numbers are one of the many types of classification of numbers. The odd numbers are not even, and the numbers which are even are not odd. Both are inverse to each other. Odd and even numbers are differentiated by whether the number is divisible by 2 or the number is a multiple of 2. An odd number, when divided by two, leaves a remainder of 1. On the other side, an even number, when divided by 2, leaves a remainder of 0. Even numbers are divisible by two and multiples of 2. Example − ... Read More
Introduction Operations of integers such as addition, subtraction, multiplication, and division can be explained in the number line system. In our daily life, we need to perform various algebraic operations with numbers. There are various types of numbers used in mathematics. In specific, the integer is a special type of number widely used. The presentation and several mathematical operations of integers are necessary. In this tutorial, we will learn about the number systems, integers, their presentation on the number line, comparison and operation of the integers on the number line with solved examples. Number System A number is a mathematical ... Read More
Introduction Operations on rational numbers such as basic operations like addition, subtraction, multiplication and division. Rational numbers are fractions containing a numerator and a denominator (the denominator should be a non-zero integer). In algebra, rational numbers are used in various science, mathematics, and economics sectors. Moreover, various operations such as addition, subtraction, division, and multiplication are necessary to obtain a third rational number. All these operations are quite different from the algebraic operations of integers. In this tutorial, we will discuss number systems, rational numbers, comparison between rational numbers, and their various operations with solved examples. Number System A number ... Read More
Introduction Ordinate is the second component in the ordered pair (x, y). There are two major branches of mathematics, including algebra and geometry. Both have separate uses and applications. However, the French mathematician Rene Descartes derived a concept through the combination of algebra and geometry. This concept helps us to express the location of any object, point, or line in the coordinate system. However, there are various topics included in the coordinate system. In this tutorial, we will learn about the coordinate system, the cartesian plane, its components (ordinate and abscissa), and some basic formulas with solved examples. Coordinate System ... Read More
The class named File of the java.io package represents a file or directory (path names) in the system. This class provides various methods to perform various operations on files/directories. The mkdir() method of this class creates a directory with the path represented by the current object. Creating directory hierarchy There are two main ways to create a directory hierarchy in Java − Using mkdirs() Method Using createDirectories() Method Let us look at these solutions one by one. Using mkdirs() Method To create a hierarchy of new directories you can using the method mkdirs() of the same class. This ... Read More
