Before we see the data types , to know the use and why its necessary.
It helps to difine type of input while we write program, its sizes and ranges , because the computer system has limited efficient memory(intelligence) compare to human intelligence. So we need to define and instruct to perform the limited memory very efficiently by using this data types. The datatype given below
The datatype has two major types 1.primitive datatype. 2.non primitive datatype
Primitive datatype the primitive data type is primary keyword(reserved words in Java).
Ex: int a=5; data type int ,reference variable a , data 5, ‘ = ‘ is assignment operator
Tomorrow we will see non primitive words thanks for reading I hope it will help you. For blog improvement give feedback in comment line.
