public final class Byte

The Byte class is the standard wrapper for byte values. Since: JDK1.1, CLDC 1.0

Fields

`public static final` `Class<Byte> TYPE`
`public static final int SIZE = 8`
`public static final byte MAX_VALUE = 127`	The maximum value a Byte can have.
`public static final byte MIN_VALUE = -128`	The minimum value a Byte can have.

Constructors

public Byte(byte value) Constructs a Byte object initialized to the specified byte value.

Methods

`public byte byteValue()`	Returns the value of this Byte as a byte.
`public boolean equals(Object obj)`	Compares this object to the specified object.
`public int hashCode()`	Returns a hashcode for this Byte.
`public static byte parseByte(String s) throws NumberFormatException`	Assuming the specified String represents a byte, returns that byte’s value.
`public static byte parseByte(String s, int radix) throws NumberFormatException`	Assuming the specified String represents a byte, returns that byte’s value.
`public` `String toString()`	Returns a String object representing this Byte’s value.
`public static` `Byte valueOf(byte i)`	Returns the object instance of i
`public int intValue()`
`public long longValue()`
`public float floatValue()`
`public double doubleValue()`
`public int compare(byte b1, byte b2)`
`public int compareTo(Byte b)`	Compares this object to the specified object to determine their relative order.

Constructor details

Byte

public Byte(byte value)

Constructs a Byte object initialized to the specified byte value. value - the initial value of the Byte

Method details

byteValue

public byte byteValue()

Returns the value of this Byte as a byte.

equals

public boolean equals(Object obj)

Compares this object to the specified object.

hashCode

public int hashCode()

Returns a hashcode for this Byte.

parseByte

public static byte parseByte(String s)
throws NumberFormatException

Assuming the specified String represents a byte, returns that byte’s value. Throws an exception if the String cannot be parsed as a byte. The radix is assumed to be 10.

Throws

NumberFormatException

parseByte

public static byte parseByte(String s, int radix)
throws NumberFormatException

Assuming the specified String represents a byte, returns that byte’s value. Throws an exception if the String cannot be parsed as a byte.

Throws

NumberFormatException

toString

public String toString()

Returns a String object representing this Byte’s value.

valueOf

public static Byte valueOf(byte i)

Returns the object instance of i

Parameters

i byte: the primitive

Returns

object instance

intValue

public int intValue()

longValue

public long longValue()

floatValue

public float floatValue()

doubleValue

public double doubleValue()

compare

public int compare(byte b1, byte b2)

compareTo

public int compareTo(Byte b)

Compares this object to the specified object to determine their relative order.

Parameters

b Byte: the object to compare to this instance.

Returns

a negative integer if this instance is less than another; a positive integer if this instance is greater than another; 0 if this instance has the same order as another.

Throws

ClassCastException: if another cannot be converted into something comparable to this instance.
