Q) what are the “primitive data types” in java language ?


A)  we have 8 primitive data types in java language.

1) int – 4 bytes 
2)float
3)double
4)char
5)Boolean
6)short - 2 bytes 
7)byte – 1 bytes 
8)long – 8 bytes 

Int , short , byte , long are non decimal integer values.
-> float and double represent decimal data types.“float“ is single precision and “double” is double precision(after decimal how many no . of values are there is called precision)

Ex :
float a=2.123456789f ;
Outout is 2.1234567 . because after decimal the float taken 7 degits are taken

Ex :
double a=2.123456789123456789 ;
Output  is 2.1234567891234567

Q) What is the purpose of JDBC?

A) -> Java application can do any task by making a method (function) call. ->java method calls are not understandable to database management system. They can understand only SQL statements. ->SQL statements can’t be directly used in a java application. Java compiler complains. ->therefore, we say that java environment and database environment are heterogeneous to each other. Purpose of JDBC: ->for any kind of java application to communicate with any kind of database (management system) in a standard manner, JDBC is used.
