Data Types in Java
Data type:
Data type indicates the different sizes and various values that can be stored in the variable.
Types of data types in Java
1.Primitive data types
2.Non-primitive data types
Java Primitive Data Types
There are 8 types of primitive data types are as follows:
★ boolean data type
★ byte data type
★ short data type
★ char data type
★ int data type
★ long data type
★ float data type
★ double data type
Java Non-Primitive Data Types
Non primitive data types are:
★Struct
★Array
★Class
Program example to understand the datatypes in java
class Datatype {
public static void main(String[] args) {
int a=23;
float b=34.5f;
long c=90l;
byte d=78;
double e=78.8;
char f='A';
short x=56;
System.out.println("Primitive Data Types:");
System.out.println("The value of int datatype is: "+a);
System.out.println("The value of float data type is: "+b);
System.out.println("The value of long data type is: "+c);
System.out.println("The value of byte data type is: "+d);
System.out.println("The value of double data type is: "+e); System.out.println("The value of char data type is: "+f);
System.out.println("The value of short data type is: "+x);
}
}
Output:
Primitive Data Types:
The value of int data type is: 23
The value of float data type is: 34.5
The value of long data type is: 90
The value of byte data type is: 78
The value of double data type is: 78.8
The value of char data type is: A
The value of short data type is: 56
