Question { NTPC, 6543 }

what are black holes?

Answer

A black hole is a concentration of mass great enough that
the force of gravity prevents anything from escaping it
except through quantum tunnelling behaviour (known as
Hawking Radiation). The gravitational field is so strong
that the escape velocity near it exceeds the speed of
light. This implies that nothing, not even light, can
escape its gravity, hence the word "black". The term "black
hole" is widespread, even though it does not refer to a
hole in the usual sense, but rather a region of space from
which nothing can return.

what is the diff between application server and data base
server?

Answer

a Web server serves pages for viewing in a Web browser,
while an application server provides methods that client
applications can call. A little more precisely, you can say
that:


A Web server exclusively handles HTTP requests, whereas an
application server serves business logic to application
programs through any number of protocols.

Question { HCL, 63426 }

What is severity and priority?Give some examples of
severity and priorty and high severity & low priority and
viceverse and also explain each.

Answer

Severity:seriousness of defect wrt to functionality

!High:without resolving the defect we r unable to continue
testing.
!Medium:compulsory to solve but able to continue
!low:May or may not be resolved.

Prority:Importance of the defect wrt customer
(High,medium,low)
When we go for examples
1.user interface bugs[low severity]
Eg1:Spelling mistake(High priority)
Eg2:Improper allignment(Low priority)

2.Input domain bugs:[medium severity]
Eg1:Doesnot allow valid values(high priority)
Eg2:allows invalid type also(low priority)

3.Race condition bugs[High severity]
Eg1:Deadlock(High priority)
Eg2:improper order or services(Low priority)
like this there r many,but the thing is that as the name
severity itself says seriousness,
based on the seriousness created by the bug we give priority
ie., importance

suggest me if there is any mistake

Question { Oracle, 11261 }

This Question asked in Oracle Walk-in
Write the content of high level design documents?
Thanks in advance

Answer

High level design document defines the overall hierarchy of
functionalities from root module 2 leaf module.After
completion of analysis and their reviews design catogery
people concentrate on logic design of application interms
of external and internal design.during hld they conduct
reviews on that document for completeness and correctness.
->is the design good?
->did they met the right requirements
->are they complete
->are they followable
->do they handle errors......

even i faced the question ......let me know if it's wrong.

Question { Persistent, 76623 }

Why Java is not purely object oriented?

Answer

Although Java is object-oriented to a great extent, it is
not a pure object-oriented language. One of the reasons
Java is not purely object-oriented is that not everything
in it is an object. For example, Java allows you to declare
variables of primitive types (int, float, boolean, etc.)
that aren't objects. And Java has static fields and
methods, which are independent and separate from objects

Question { A1 Technology, 319517 }

What are the OOPS concepts?

Answer

1) Encapsulation: It is the mechanism that binds together
code and data in manipulates, and keeps both safe from
outside interference and misuse. In short it isolates a
particular code and data from all other codes and data. A
well-defined interface controls the access to that
particular code and data.
2) Inheritance: It is the process by which one object
acquires the properties of another object. This supports
the hierarchical classification. Without the use of
hierarchies, each object would need to define all its
characteristics explicitly. However, by use of inheritance,
an object need only define those qualities that make it
unique within its class. It can inherit its general
attributes from its parent. A new sub-class inherits all of
the attributes of all of its ancestors.
3) Polymorphism: It is a feature that allows one interface
to be used for general class of actions. The specific
action is determined by the exact nature of the situation.
In general polymorphism means "one interface, multiple
methods", This means that it is possible to design a
generic interface to a group of related activities. This
helps reduce complexity by allowing the same interface to
be used to specify a general class of action. It is the
compiler's job to select the specific action (that is,
method) as it applies to each situation

Question { 9999 }

What is Method overloading?

Answer

Method overloading occurs when a class contains two methods
with the same name, but different signatures

Question { 7656 }

In which cases you use override and new base?

Answer

Use the new modifier to explicitly hide a member inherited
from a base class. To hide an inherited member, declare it
in the derived class using the same name, and modify it
with the new modifier.

Question { 9258 }

You have one base class virtual function how will call that
function from derived class?

Answer

class a
{
public virtual int m()
{
return 1;
}
}
class b:a
{
public int j()
{
return m();
}
}

Question { InfoAxon Technologies, 10617 }

In which Scenario you will go for Interface or Abstract Class?

Answer

Interfaces, like classes, define a set of properties,
methods, and events. But unlike classes, interfaces do not
provide implementation. They are implemented by classes,
and defined as separate entities from classes. Even though
class inheritance allows your classes to inherit
implementation from a base class, it also forces you to
make most of your design decisions when the class is first
published.
Abstract classes are useful when creating components
because they allow you specify an invariant level of
functionality in some methods, but leave the implementation
of other methods until a specific implementation of that
class is needed. They also version well, because if
additional functionality is needed in derived classes, it
can be added to the base class without breaking code.

Question { 12729 }

difference between memcpy and strcpy

Answer

A. memcpy can copy null bytes also if the size of memory is
given
strcpy stops after the first null byte.
