final public static String	toString(int value) Returns a string representation of the specified `int`.
final public static String	toString(long value) Returns a string representation of the specified `long`.
final public static String	toString(float value) Returns a string representation of the specified `float`.
final public static String	toString(double value) Returns a string representation of the specified `double`.

Field Detail

FALSE
final public static String FALSE(Code)
	Canonical string representation of `false`.

TRUE
final public static String TRUE(Code)
	Canonical string representation of `true`.

Method Detail

isInt
final public static boolean isInt(String value)(Code)
	Returns `true` if the value can be parsed to an `int`. Parameters: value - string representation of the `int` `true` if argument is an `int`;otherwise `false`

toBoolean
final public static boolean toBoolean(String value)(Code)
	Returns the `boolean` value represented by the specified string, ignoring case. If the value is neither `"true"`, nor `"false"` (ignoring case), an `IllegalArgumentException` is thrown. Note: This implementation is different than the `java.lang.Boolean` implementation. The `java.lang.Boolean` treats `null` and any non-`"true"` value (ignoring case) as `false`, i.e., there is no validation of `false` values. Parameters: value - string representation of a boolean value `boolean` value represented by the argument throws: IllegalArgumentException - if value is (ignoring case)neither `"true"`, nor `"false"`

toByte
final public static byte toByte(String value)(Code)
	Returns a signed decimal `byte` value. The characters in the string must all be decimal digits, except that the first character may be an ASCII minus sign '-' ('\u002D') to indicate a negative value. Parameters: value - string representation of a `byte` value `byte` value represented by the argument throws: IllegalArgumentException - if argument is not a parseable`byte`

toChar
final public static char toChar(String value)(Code)
	Returns the first character of the string. Parameters: value - string representation of the `char` `char` representation of the argument throws: IllegalArgumentException - if `value` is`null` or of zero length

toDouble
final public static double toDouble(String value)(Code)
	Returns a new double initialized to the value represented by the specified String, as performed by the valueOf method of class Double. Parameters: value - string representation of the `long` `long` representation of the argument throws: IllegalArgumentException - if string does not contain aparseable `long`

toFloat
final public static float toFloat(String value)(Code)
	Returns a new float initialized to the value represented by the specified String, as performed by the valueOf method of class Double. Parameters: value - string representation of the `long` `long` representation of the argument throws: IllegalArgumentException - if string does not contain aparseable `long`

toHexString
final public static String toHexString(byte[] values)(Code)
	Returns a hexidecimal string representation of the specified byte array. Parameters: values - `byte` array to be converted hexidecimal string representation of argument

toHexString
final public static String toHexString(long value)(Code)
	Converts a long value to a hexidecimal string. Parameters: value - long to be converted string representation of the long value

toInt
final public static int toInt(String value)(Code)
	Parses the string argument as a signed decimal integer. The characters in the string must all be decimal digits, except that the first character may be an ASCII minus sign '-' ('\u002D') to indicate a negative value. Parameters: value - string representation of the `int` `int` representation of the argument throws: IllegalArgumentException - if string does not contain aparseable `int`

toLong
final public static long toLong(String value)(Code)
	Parses the string argument as a signed long in the radix specified by the second argument. The characters in the string must all be digits of the specified radix (as determined by whether Character.digit returns a nonnegative value), except that the first character may be an ASCII minus sign '-' ('\u002d' to indicate a negative value. The resulting long value is returned. Note that neither L nor l is permitted to appear at the end of the string as a type indicator, as would be permitted in Java programming language source code. Parameters: value - string representation of the `long` `long` representation of the argument throws: IllegalArgumentException - if string does not contain aparseable `long`

toShort
final public static short toShort(String value)(Code)
	Returns the `short` representation of the specified string. The characters in the string must all be decimal digits, except that the first character may be an ASCII minus sign '-' ('\u002D') to indicate a negative value. Parameters: value - string representation of the `short` `short` representation of the argument throws: IllegalArgumentException - if argument is not a parseable`short`

toString
final public static String toString(boolean value)(Code)
	Returns a canonical `String` object representing the specified `boolean`. If the value is `true`, the string `"true"` will be returned; if the value is `false`, the string `"false"`. Parameters: value - `boolean` value to be converted canonical string representation of the`boolean` value

toString
final public static String toString(byte value)(Code)
	Returns a string representation of the argument of radix 10. Parameters: value - `byte` value to be converted string respresentation of the argument

toString
final public static String toString(char value)(Code)
	Returns a string representation of the argument. The result string of length 1 consisting solely of the specified char. Parameters: value - `char` value to be converted string representation of the argument

toString
final public static String toString(short value)(Code)
	Returns a string representation of the specified `short` value of radix 10. Parameters: value - `short` value to be converted string representation of the argument

toString
final public static String toString(int value)(Code)
	Returns a string representation of the specified `int`. Parameters: value - `int` >value to be converted string representation of the argument

toString
final public static String toString(long value)(Code)
	Returns a string representation of the specified `long`. Parameters: value - `long` value to be converted string representation of the argument

toString
final public static String toString(float value)(Code)
	Returns a string representation of the specified `float`. Parameters: value - `float` value to be converted string representation of the argument

toString
final public static String toString(double value)(Code)
	Returns a string representation of the specified `double`. Parameters: value - `double` value to be converted string representation of the argument
