Interests Interview Questions
Do you prefer working alone or in groups ? (service industry)
Effect of frequency on an equipment
What will happen if a motor designed for 230 volts 50 hz is connected to a supply of 230 volts 400 hz
Changing frequency will change the speed of motor, suppose in case of induction motor, speed of motor is proportional to its frequency. Doubling the frequency doubles the speed.
How to introduce ourselves and what is the format for self introduction ?
Where do you see yourself in five years
What do mean by polymorphism, inheritance, encapsulation?
Polymorhism: is a feature of oopl that at run time depending upon the type of object the appropriate method is called.Inheritance: is a feature of oopl that represents the "is a" relationship between different objects(classes). Say in real life a manager is a employee. So in oopl manger class is inherited...
polymorphism: it is used to derive the class one in many form
inheritance: deriving the neq class from the existing class
encapsulation: hiding the information
What has been the most important person or event in your own self development?
Many people have contributed to my learning and growth over the years both personally and through books that I've read. The MOST IMPORTANT person (besides myself of course) would be my fathe...
People around me and the mistake i made helped me a lot to character correction(self developmet).
How does multithreading take place on a computer with a single cpu?
The operating system's task scheduler allocates execution time to multiple tasks. By quickly switching between executing tasks, it creates the impression that tasks execute sequentially.
On a single processor, Multithreading generally occurs by time-division multiplexing ("time slicing") in very much the same way as the parallel execution of multiple tasks (computer multitas...
What do you mean by multiple inheritance in C++ ?
Multiple inheritance is a feature in C++ by which one class can be of different types. Say class teachingassistant is inherited from two classes say teacher and student.
A derived class if it inherits from more than one direct base class,it is call multiple inheritance.
Write the Java code to declare any constant (say gravitational constant) and to get its value?
Class abc{static final float gravitational_constant = 9.8;public void getconstant(){system.Out.Println("gravitational_constant: " + gravitational_constant);}}
class abc
{
final const float PI=3.14f;
}
What do you mean by static methods?
By using the static method there is no need creating an object of that class to use that method. We can directly call that method on that class. For example, say class a has static function f(), then we can call f() function as a.F(). There is no need of creating an object of class a.
static methods are class methods. in which we can use only static data varibles of any calss of the program. these methods are invoke with out create objects of corresponding the class.
Select student.Name, student.Sidfrom student, levelwhere student.Sid = level.Sidand level.Level = "freshman"and student.Course = 3;
I think this is the right answer of the above query:
SELECT Student.name, Student.SID FROM Student, Level
select Name,SID from student
where Course=3 and SID in ( select SID from Level where Level='freshman' )
What is the difference between serializalble and externalizable interface?
When you use serializable interface, your class is serialized automatically by default. But you can override writeobject() and reADObject()two methods to control more complex object serailization process. When you use externalizable interface, you have a complete control over your class's serialization...
Java gives you control over the serialization process through the java.io.Externalizable interface. The java.io.Externalizable interface extends the java.io.SerialiJava gives you control over the seri...
What kind of books & other publications do you read?
Have you taken a management development course?
How are you helping your subordinates develop themselves?
What are the advantages of oopl?
Object oriented programming languages directly represent the real life objects. The features of oopl as inhreitance, polymorphism, encapsulation makes it powerful.
What do you mean by virtual methods?
Virtual methods are used to use the polymorhism feature in c++. Say class a is inherited from class b. If we declare say fuction f() as virtual in class b and override the same function in class a then at runtime appropriate method of the class will be called depending upon the type of the object.
What are the disadvantages of using threads?
Deadlock.
Can you write Java code for declaration of multiple inheritance in Java ?
Class C extends a implements b{}
What are the object and class classes used for?
The object class is the highest-level class in the Java class hierarchy. The class class is used to represent the classes and interfaces that are loaded by a Java program.

I believe that working in groups improves the productivity as there are multiple brains working together for achieving the objective and ofcourse creativity level will shoot up.
