Data Types in Java

 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
