Discrete and continuous data are a part of statistical analysis. Businesses have to measure the quantitative data which helps them to know about the products and services that they are providing. In this article, we will discuss the difference between discrete data and continuous data which are quantitative. What is Discrete Data? Discrete data is a type of data which is limited to only certain types of values. The number of values is limited and is in the form of integers or whole numbers. These values belong to those categories which cannot be further broken down. Uses of Discrete Data ... Read More
Dual Core Processors and Core 2 Duo Processors are CPUs whose job is to process data as per request. A dual-core processor comes with two cores while a core 2 duo processor is a series of dual-core processors. In this article, we will see the difference between Dual-Core and Core 2 Duo Processors. What is a Dual Core Processor? The main aim of making a computer was to solve different types of mathematical problems. The data processing speed of the first computers was very slow. Another disadvantage was that they could run only one process at a time so other ... Read More
To create toggle switch by using HTML and CSS, we will be using simple HTML input elements and CSS for styling the toggle box to make it user intercative. A toggle switch is a graphical user interface element that allows users to toggle between two states, usually 'on' and 'off'. In this article we are going to understand how to create toggle switch by using HTML and CSS. We are having an input tag with type attribute value as checkbox. Our task is to design this checkbox and create a toggle switch by using HTML and CSS. We will be ... Read More
In general, Java Array is a collection of homogeneous elements and Streams are sequence of objects from a source, which supports aggregate operations. We can create a IntStream object holding a sequence of integer values. To convert the integer array to an IntStream object you need to use the Arrays.stream() method. IntStream: The IntStream extends the BaseStream interface. It defines the stream of primitive integer value. We can import the IntStream class from java.util package. The Arrays.stream() method The Arrays.stream() method creates a sequential stream from an array. It is a static method in the Arrays. Following is the syntax ... Read More
Binary Number − There are many types of number systems depending upon the base value. Binary numbers are one of them. The Binary number is basically represented by two digits i.e. one (1) and zero (0). The binary numbers are expressed as base-2 in the numeral system. Octal Number − Octal number is also one of the number systems available. The octal number is represented with 8 digits which is from 0 to 7(0, 1, 2, 3... 7). The Octal numbers are expressed as base-8 in the numeral system. Here we are converting the Binary number to an octal number ... Read More
Generally, Data about data is known as metadata. The DatabaseMetaData interface provides methods to get information about the database you have connected with like, database name, database driver version, maximum column length, etc... The getMetaData() method of the Connection interface retrieves and returns the DatabaseMetaData object. This contains information about the database you have connected to. You can get information about the database such as the name of the database, version, driver name, user name, URL, etc… by invoking the methods of the DatabaseMetaData interface using the obtained object. This method returns the DatabaseMetaData object which holds information about the underlying ... Read More
In general, the endswith() method in Java is used to check whether the given string ends with a specific suffix string or not. If the substring ends with the specific string then it will return a Boolean value true, otherwise it will return false if the value is not found.

Read the base and exponent values from the user. Multiply the base number by itself and multiply the resultant with base (again) repeat this n times where n is the exponent value. 2 ^ 5 = 2 X 2 X 2 X 2 X 2 (5 times) Problem Statement Given a number, write a program in Java to calculate the power of the number − Input Enter the base number :: 12 Enter the exponent number :: 2 Output Result of 12 power 2 is 144 Steps to calculate the power of a number Import ...
