Answers to common questions asked in a Software Tester interview.

SDLC process involves planning, designing, coding, testing, and deployment of software.
Adhoc testing is informal testing without predefined test cases.
Regression testing involves retesting unchanged parts of the software after modifications.
Sanity testing checks if the software is stable enough for further testing.
OOP's concept includes classes, objects, inheritance, polymorphism, and encapsulation.
Exploratory testing involves simultaneous learning, test design, and test execution.
User testing involves real users testing the software for usability and functionality.
A Java program for leap year: public class LeapYear { public static void main(String[] args) { int year = 2024; if((year % 4 == 0 && year % 100 != 0) || (year % 400 == 0)) { System.out.println(year + " is a leap year."); } else { System.out.println(year + " is not a leap year."); } } }
A constructor is a special type of method that is used to initialize objects.
An overloader is a method in a class that has the same name as another method but different parameters.
