The byte keyword in Java programming language

In this tutorial, we will discuss the byte keyword in Java programming language

Varaible declaration

The byte keyword can be used to declare a variable in Java

syntax

The syntax of byte keyword for variable declaration

byte <variable_name>=<integer_value>;

Example

This is an example for the variable declaration of byte keyword

byte month=19;  //or
byte value='c'  //The number 99 is the value for 'c'(small) in ASCII

Method declaration

The byte keyword can be used to declare a return type method in Java

public byte getMyAge(){
return 28;
}

Here is an Example

Program 1

public class Byte_example{

  public static void main(String args[]){
  int age=18;
  System.out.print("my age is :");
  System.out.println(age);
  
  
  }
}

 

When the above code is executed, it produces the following results

 

my age is :18

 

Program 2

Find ASCII value using byte

public class Byte_example1{

  public static void main(String args[]){
  int find_ASCII_1='c';
  int find_ASCII_2='C';
  System.out.println("Find ASCII value of C :"+find_ASCII_2);
  System.out.print("Find ASCII value of c :"+find_ASCII_1);
  
  
  }
}

 

When the above code is executed, it produces the following results

Find ASCII value of C :67
Find ASCII value of c :99
