moka.lang.Long
The Long class wraps a value of the primitive type long
in an object. An object of type long
contains a
single field whose type is long
.
In addition, this class provides several methods for converting
an long
to a String
and a
String
to an long
, as well as other
constants and methods useful when dealing with an
long
.
Field Summary | |
static long |
MAX_VALUE
A constant holding the maximum value a long can
have, 263-1. |
static long |
MIN_VALUE
A constant holding the minimum value a long can
have, -263. |
Constructor Summary | |
Long(long value)
Constructs a newly allocated Long object that
represents the primitive long argument. |
|
Long(String s)
Constructs a newly allocated Long object that
represents the value represented by the string. |
Method Summary | |
byte |
byteValue()
Returns the value of this Long as a byte . |
double |
doubleValue()
Returns the value of this Long as a double . |
boolean |
equals(Object obj)
Compares this object to the specified object. |
int |
intValue()
Returns the value of this Long as an int . |
static boolean |
isLong(String str)
Checks if the specified string is a decimal representation of a long integer. |
long |
longValue()
Returns the value of this Long as an
long . |
static long |
parseLong(String s)
Parses the string argument as a signed decimal long. |
short |
shortValue()
Returns the value of this Long as a short . |
String |
toString()
Returns a String object representing this
Long 's value. |

Constructor Detail |
public Long(long value)
Long
object that
represents the primitive long
argument.
value
- the value to be represented by the long
.public Long(String s)
Long
object that
represents the value represented by the string. The string is
converted to an long in exactly the manner used by the
parseLong method.
s
- the String
to be converted to an
Long
.Method Detail |
public String toString()
String
object representing this
Long
's value. The value is converted to signed
decimal representation and returned as a string, exactly as if
the long value were given as an argument to the valueOf method
of String.
toString
in class Object
public boolean equals(Object obj)
true
if and only if the argument is not
null
and is an Long
object that
contains the same long
value as this object.
equals
in class Object
obj
- the object to compare with.
true
if the objects are the same;
false
otherwise.public long longValue()
Long
as an
long
.
public static long parseLong(String s)
'-'
('\u002D'
) to indicate a negative value. The resulting
integer value is returned. The string argument is finalized before the method
returns.
s
- a String
containing the long
representation to be parsed
