byte keyword in java

The byte keyword is used to declare variable as a numeric type.

A byte value can hold an 8-bit integer number which ranges from -128 to 127.

For example:
byte day = 6;

The byte keyword can be used to declare a type of a method parameter as below:

1
2
3
4
5
6
7
8
public void displayDayOfWeek(byte day) {
 
    if(day == 3){
 
                   System.out.println("Tuesday");
                }
 
}
public void displayDayOfWeek(byte day) {

    if(day == 3){

                   System.out.println("Tuesday");
                }

}


The byte keyword can also be used to declare return type of a method as below:

1
2
3
4
5
6
7
public byte getDayOfWeek(String day) {
 
if(day.equals("Monday")){    
 
                              return 2;
                        }
}
public byte getDayOfWeek(String day) {

if(day.equals("Monday")){    

                              return 2;
                        }
}
