In this lesson, we will learn, what is Byte Variable and how it works in Java programming along with some examples.

Declare a byte variable x.

byte x;

Declare a byte variable x to assign a byte value 10.

byte x = 10;

Declare 3 byte variables x, y and z in a single line.

byte x, y, z;

Declare 3 byte variables x, y and z to assign the byte value 42, 67 and 85 respectively in a single line.

byte x=42, y=67, z=85;

Declare a byte variable x and assign the byte value 18 in the second line.

byte x;
x = 18;

Declare a byte variable x and assign the byte value 76 and change its value to 54 in the next line.

byte x = 76;
x = 54; // now the new value of x is 54
