Using the StringBuffer class To add underscore before each capital letter in a String using StringBuffer − Create an empty StringBuffer object. The isUpperCase() method of Character class accepts a character and verifies whether it is in upper case, if so, this method returns true. Using this method, verify each character in the String. In case of upper case letter append underscore before it, using the append() method. Example public class Adding_BeforeCapital { public static void main(String args[]) { String str = "HelloHowAreYouWelcome"; StringBuffer sb = new StringBuffer(); for ... Read More
Let’s say the following is our list of characters − List list = Arrays.asList('W', 'e', 'l', 'c', 'o', 'm', 'e'); Convert the list of characters to string − String string = list.stream().map(String::valueOf).collect(Collectors.joining()); Example Following is the program to convert List of Characters to String in Java − import java.util.stream.Collectors; import java.util.Arrays; import java.util.List; public class Demo { public static void main(String[] args) { List list = Arrays.asList('W', 'e', 'l', 'c', 'o', 'm', 'e'); String string = list.stream().map(String::valueOf).collect(Collectors.joining()); System.out.println("String = "+string); } } Output String = Welcome Read More

Definition of CNG Compressed Natural Gas (CNG) is a fuel that is made by compressing natural gas to a pressure of about 3600 pounds per square inch or higher, which makes it easier to store and transport. It is primarily composed of methane gas and is extracted from natural gas reserves often found in underground rock formations. Extraction and Production of CNG Compressed Natural Gas (CNG) is extracted from underground reservoirs often found in rock formations, using a process called drilling. The process involves drilling a well into the earth’s surface to reach the natural gas reservoir, and then ... Read More
Introduction Digital Addressable Controller (DAC) main objective is to make it possible to precisely manage and automate equipment for use in a variety of applications, including lighting control systems, building automation, business operations, and more. The DAC enables targeted and customised management, monitoring, and configuration of the linked devices by allocating digital addresses to each one. In actuality, lighting control systems frequently employ DACs to give unique addresses to light fixtures or lighting control modules. This enables energy economy and personalised lighting scenarios by offering fine-grained control over each light source, including dimming, colour modification, and scheduling. ... Read More
Introduction DAMPS (Digital Advanced Mobile Phone Service) is a cellular technology that was first made available in the US in the 1980s. It provided voice communication services to users of mobile phones and was the main commercially available cellular network in the US. DAMPS used analogue transmission, which at the time was the industry standard for cellular networks. Later, modern cellular systems took its place, which had a few advantages over analogue ones such as improved call quality, increased capacity, and improved security. DAMPS was developed by the American Telephone & Telegraph (AT&T) business, which at the time ... Read More
Introduction Direct Broadcast Satellite (DBS) transmission technology delivers television and radio signals directly to households and businesses. In order to receive signals from satellites in geostationary orbit, DBS uses smaller dish antennas, often with a diameter of less than a meter. The signals are scrambled, encrypted, and transmitted across a specific frequency band to the receiving antenna, where they are decrypted and shown on the TV. In locations where cable or terrestrial television service is limited or insufficient, DBS systems are popular because they may provide an extensive range of channels, including high-definition content. Internet services and other multimedia ... Read More
Introduction Database Source Name (DBSN) is recognized as a unique identification of (Database Management System (DBMS). When several databases are hosted on a single DBMS, it is used to establish a connection to a particular database. The database name, host name or IP address of the server where the database is hosted, and the port number used to access the database are all included in the DBSN. To connect to databases and perform database activities, it is frequently used in programming languages and applications. Importance of DBSN in database connectivity The Database Source Name, or DBSN, is important ... Read More
Introduction Data Flow Diagram (DFD) is a perspective model of the flow of data through the process by which the user can understand it easily. By this DFD the system is represented graphically and aimed to reach the concept for both computer specialists and non-specialists in the same way. During specification and analysis of the requirements, DFD helps software engineers, users, and customers to work together. What is DFD? The full form of DFD is Data Flow Diagram. It was made popular by Larry Constantine and Edward Yourdon in the late 1970s. The computational base model “Data ... Read More
Introduction Digital Fuel Injection (DFI) system is programmed to precisely enrich the cold-start mixture so that the portion of the fuel that can vaporise at low temperatures is present in enough quantity to create an ignitable mixture (this so-called "front end" of the fuel is primarily a small volatile species called isopentane). The EPA wants the exhaust catalyst to be near to the engine and ready to "light off" as quickly as possible since the remaining gasoline travels through the engine unburned. Adoption of Gasoline Direct Injection (GDI) in favour of traditional port injection is another stage. Atomized ... Read More
