Introduction Capacitor Discharge Ignition (CDI) is an electronic ignition system that uses a high voltage electrical discharge from a capacitor to ignite the fuel mixture in the combustion chamber of an internal combustion engine. CDI systems offer several advantages over traditional contact breaker points, including improved ignition timing accuracy, higher energy spark, and increased reliability. In a CDI system, the ignition coil is charged with energy from the battery, and when the spark plug needs to fire, the energy is rapidly released from the capacitor to create a high voltage electrical discharge. This results in a powerful spark that ... Read More
Introduction The UNFCCC and CDM are mechanisms based on projects that enable developed nations to compensate for their greenhouse gas emissions by funding emission-reducing projects in developing nations. The CDM was created to encourage long-term development and technology transfer, as well as to lower greenhouse gas emissions. No information has been omitted from the original text. What is Carbon Credit? A certificate known as a carbon credit permits an organization or country to release a specified amount of greenhouse gases, including carbon dioxide, into the atmosphere. These credits were designed to encourage the reduction of greenhouse gas emissions ... Read More
Introduction Code Division Multiple Access (CDMA) is a wireless communication technology that enables multiple users to share the same frequency band. Each user in a CDMA system is assigned a unique code that helps in modulating their signal. The code isolates the user's message from other messages in the same frequency band, allowing multiple users to transmit and receive data concurrently without causing any interference. Although CDMA was initially developed by the military in the 1940s, it was only in the 1980s that it was commercialized and widely used in mobile phone networks. Nowadays, CDMA is utilized in several ... Read More
Yes, the protected method of a superclass can be overridden by a subclass. If the superclass method is protected, the subclass overridden method can have protected or public (but not default or private) which means the subclass overridden method can not have a weaker access specifier. Example class A { protected void protectedMethod() { System.out.println("superclass protected method"); } } class B extends A { protected void protectedMethod() { System.out.println("subclass protected method"); } } public class Test { public static void main(String args[]) { B b = new B(); b.protectedMethod(); } } Output subclass protected method
A Locale class is used to perform locale operations and supply locale information to the user. A Locale is defined as a set of parameters that represents a geographical location or place where some operation occurs. The important methods of Locale class are getAvailableLocales(), getCountry(), getDefault(), getDisplayLanguage(), getDisplayCountry(), getUnicodeLocaleKeys() etc. The Locale class uses the following constructors − Locale(String L)− Initializes locale from the language code passed as an argument. Locale(String L, String C) − Initializes locale from the language, country code passed as arguments. Locale(String L, String C, String V) − Initializes locale from the language, country, variant passed as arguments. Example import java.text.SimpleDateFormat; import java.util.Locale; public ...

The Serialization is a process of changing the state of an object into a byte stream, an object is said to be serializable if its class or parent classes implement either the Serializable or Externalizable interface and the Deserialization is a process of converting the serialized object back into a copy of an object. During serialization, if we don’t want to write the state of a particular variable in a byte stream using a transient keyword. When the JVM comes up to the transient keyword, it ignores the original state of a variable and stores a default value of that data type ... Read More
A HashSet implements Set interface which does not allow duplicate values. A HashSet is not synchronized and is not thread-safe. When we can add any duplicate element to a HashSet, the add() method returns false and does not allow to add a duplicate element to HashSet. Syntax public class HashSet extends AbstractSet implements Set, Cloneable, Serializable In the below example, we can implement a Custom HashSet. Example import java.util.*; public class CustomHashSetTest extends AbstractSet { private HashMap map = null; private static final Object tempObject = new Object(); public CustomHashSetTest() { map = new HashMap(); ...

Whenever we want to stop a thread from running state by calling stop() method of Thread class in Java. This method stops the execution of a running thread and removes it from the waiting threads pool and garbage collected. A thread will also move to the dead state automatically when it reaches the end of its method. The stop() method is deprecated in Java due to thread-safety issues. Syntax @Deprecated public final void stop() Example import static java.lang.Thread.currentThread; public class ThreadStopTest { public static void main(String args[]) throws InterruptedException { UserThread userThread = new UserThread(); ...

Introduction Corporate Debt Restructuring (CDR) is a process where a company arranges with its banks to rebuild the terms of its exceptional debt to improve its financial circumstances. CDR is typically done when a company is encountering financial trouble and is incapable of meeting its debt commitments. The rebuilding can include measures such as amplifying the repayment period, reducing the intrigued rate, or converting obligation into equity. The objective of CDR is to provide relief to the company from its obligation burden, improve its cash flow and productivity, and ultimately, ensure its long-term reasonability. CDR is a complex process ... Read More
