Data types

What is primitive data type in java

Primitive types are the most basic data types available within the Java language. There are 8: boolean , byte , char , short , int , long , float and double . These types serve as the building blocks of data manipulation in Java. Such types serve only one purpose — containing pure, simple values of a kind.

         #numeric -int,float,complex,bool
         #sequences- list,tuple,set,string,range
         #loops - for and while
         #condition- ==,<,>,<=,>=
         #functions(methods)

Data types

#simple intrest in python
P=float(input('principle amount:'))
R=float(input('rate:'))
T=int(input('Time:'))
SI=(P*R*T)/100
print('simple intrest=',SI)
#output:
principle amount:
rate:
Time:

What are the data types

• number(num) - whole numbers up to num digits
• number(num,num2) - num whole numbers up to num2 decimals
• char(num) - fixed length character/string
• varchar2(num) - used for varying length data
• date - full date
• currency - used for prices

Data type

[0]
In computer science and computer programming, a data type or simply type is
anattribute of data which tells the compiler or interpreter how the 
programmer intends to use the data. Most programming languages support basic
data types of integer numbers (of varying sizes), floating-point numbers 
(which approximate real numbers), characters and Booleans. A data type 
constrains the values that an expression, such as a variable or a function, 
might take. This data type defines the operations that can be done on the
data, the meaning of the data, and the way values of that type can be
stored. A data type provides a set of values from which an expression 
(i.e. variable, function, etc.) may take its values.


[1]
Data types are used within type systems, which offer various ways of
defining, implementing, and using them. Different type systems ensure varying
degrees of type safety.

Almost all programming languages explicitly include the notion of data type,
though different languages may use different terminology.

Common data types include:

Integer
Floating-point number
Character
String
Boolean
