introduction

the java.lang.byte class wraps a value of primitive type byte in an object. an object of type byte contains a single field whose type is byte.

class declaration

following is the declaration for java.lang.byte class −

public final class byte
   extends number
      implements comparable<byte>

field

following are the fields for java.lang.byte class −

  • static byte max_value − this is constant holding the maximum value a byte can have, 27-1.

  • static byte min_value − this is constant holding the minimum value a byte can have, -27.

  • static int size − this is the number of bits used to represent a byte value in two's complement binary form.

  • static class<byte> type − this is the class instance representing the primitive type byte.

class constructors

sr.no. constructor & description
1

byte(byte value)

this constructs a newly allocated byte object that represents the specified byte value.
2

byte(string s)

this constructs a newly allocated byte object that represents the byte value indicated by the string parameter.

class methods

sr.no. method & description
1 byte bytevalue()

this method returns the value of this byte as a byte.
2 int compareto(byte anotherbyte)

this method compares two byte objects numerically.
3 static byte decode(string nm)

this method decodes a string into a byte.
4 double doublevalue()

this method returns the value of this byte as a double.
5 boolean equals(object obj)

this method compares this object to the specified object.
6 float floatvalue()

this method returns the value of this byte as a float.
7 int hashcode()

this method returns a hash code for this byte.
8 int intvalue()

this method returns the value of this byte as an int.
9 long longvalue()

this method returns the value of this byte as a long.
10 static byte parsebyte(string s)

this method parses the string argument as a signed decimal byte.
11 static byte parsebyte(string s, int radix)

this method parses the string argument as a signed byte in the radix specified by the second argument.
12 short shortvalue()

this method returns the value of this byte as a short.
13 string tostring()

this method returns a string object representing this byte's value.
14 static string tostring(byte b)

this method returns a new string object representing the specified byte.
15 static byte valueof(byte b)

this method returns a byte instance representing the specified byte value.
16 static byte valueof(string s)

this method returns a byte object holding the value given by the specified string.
17 static byte valueof(string s, int radix)

this method returns a byte object holding the value extracted from the specified string when parsed with the radix given by the second argument.
