Write a program to reverse an array in Java? In this tutorial, we will write a Java program to reverse an array. Before writing the program to reverse the array, we look into some basics of an array. Some basics Array is used for storing groups of variables. An array is a group of variables that […]
Difference between System Testing and Acceptance Testing Let’s loot at some of the differences between System Testing and Acceptance testing in this post. System Testing System testing tests the whole system. System testing checks the whole application. All the modules need to be integrated before system testing. The overall product is tested to show that […]
Difference between an Abstract class and an Interface? Let’s discuss some differences between an abstract class and an interface in Java. Interfaces provide the flexibility for unrelated classes to implement multiple interfaces. In Java, both abstract classes and interfaces are used to achieve abstraction — a core concept in object-oriented programming that allows you to […]
Mathematical Induction Example Proof statement Problem Statement: Using Mathematical Induction, prove that for n > 1, the following formula holds true: Mathematical Proof: First of all, we will prove for the base case n=2. LHS = RHS = Both LHS and RHS ( Left hand side and Right hand side ) are […]
Difference between Error and Exception? Let’s learn the difference between Error and Exception. Error Errors indicate serious problems or abnormal conditions in the application. The application might not catch or handle the error and may lead to an application crash. public class Error extends Throwable { Error and its subclasses are regarded as unchecked exceptions. […]
What is Mathematical Induction? Mathematical induction is a method to prove that some statement about the integer n is true for all n. In this method, first, we prove the statement when n has its smallest value, say p0. This is called the base case or basis or trivial case. Then you prove the […]
