Byte Class Fields in Java with example

Last Updated : 11 Jul, 2025

Byte class is a wrapper class for the primitive type byte which contains several methods to effectively deal with a byte value like converting it to a string representation, and vice-versa. An object of Byte class can hold a single byte value. Byte class offers four constants in the form of Fields. These are:

MAX_VALUE:The MAX_VALUE is a instance variable of Byte class which is used to return the maximum byte value. Syntax:
```
public static final byte MAX_VALUE
```
Usage:
```
Byte.MAX_VALUE
```
Return Value: It returns a byte value equal to 127. Below is the implementation of MAX_VALUE:
Output:
```
127
```
MIN_VALUE:The MIN_VALUE is a instance variable of Byte class which is used to return the minimum byte value. Syntax:
```
public static final byte MIN_VALUE
```
Usage:
```
Byte.MIN_VALUE
```
Return Value: It returns a byte value equal to -128. Below is the implementation of MIN_VALUE:
Output:
```
-128
```
SIZE:The SIZE is a instance variable of Byte class which is used to return number of bits required to represent a byte value in binary representation (two's complement). Syntax:
```
public static final int SIZE
```
Usage:
```
Byte.SIZE
```
Return Value: It returns a int value equal to 8. Below is the implementation of SIZE:
Output:
```
8
```
TYPE: The TYPE is a instance variable of Byte class which is used to return Class instance representing the primitive data type byte. Syntax:
```
public static final Class<Byte> TYPE
```
Usage:
```
Byte.TYPE
```
Return Value: It returns an Class instance representing the primitive data type byte. Below is the implementation of TYPE:
