Class are the blueprint of an object.
Explanation:
Following are the points regarding class in c++
1.In C++ class is an user defined datatype..
2.Classes are the collection of variable and function in c++.
3.To access the property of class we can create object of that class
4.We can use following syntax to declared any class in c++
class classname
{
accessmodifier:
//statement and function
};
main()
{
classname objectname;
}
implementation of class in c++
#include<iostream>
class test // class declaration
{
public: // access modifier
void fun3() // Method definition
{
cout<<" hello :";
}
};
void main() // main function
{
test ob;// creating object
ob.fun3(); // calling function
}
In this program we declared a class "test " in class test. We giving public access modifier .The public access modifier define that variable and function are accessible outside the class and in main method we create the object ob which call the function fun3().
Output:hello :

Explanation:
In java there are eight primitive data types has a class dedicated, and then we can find eight wrapper classes, I'm going to let you the next table with the 8 example:
Assume the next table byte and Int are primitive data, the different with byte is only the capital letter Byte.
Primitive Wrapper Class
boolean Boolean
byte Byte
char Character
int Integer
float Float
double Double
long Long
short Short
I think the question is referring to the tab key.
Answer:
