3.what is a class.

int Age;
void displaystdName();
int getAge(char stdName);
}

4.How java enable high performance?

9.Difine packages in java?
A package can be defined as a groping of related types(classes, interface, enumerations and annotations) providing access protection and name space management.
10.why packages are used?
packages are used in java in-order to prevent naming conflicts, to controls access, to make searching/location and usage of classes, interfaces, enumerations and annotations, etc. easier .

Hi There,
ReplyDeleteZoooooooom! That’s how speedy and easy this read was! Looking forward to more of such powerful content on C++ interview questions!
I have a 1.7 year of exp in C. I wanted to develop a project from job point of view which can make a resume much stronger.
If a program is large, it is subdivided into a number of smaller programs that are called modules or subprograms. If a complex problem is solved using more modules, this approach is known as modular programming.
Very useful article, if I run into challenges along the way, I will share them here.
Obrigado,
Lee
