public StringConversions()

Method Detail

toInt

public static int toInt(String s)

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. The resulting integer value is returned, exactly as if the argument and the radix 10 were given as arguments to the #parseInt(java.lang.String, int) method.

Parameters:

s - a String containing the int representation to be parsed

Returns:

the integer value represented by the argument in decimal.

Throws:

NumberFormatException - if the string does not contain a parsable integer.

See Also:

Integer.parseInt(String)

toLong

public static long toLong(String s)

Parses the string argument as a signed decimal long. 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. The resulting long value is returned, exactly as if the argument and the radix 10 were given as arguments to the #parseLong(java.lang.String, int) method.

Note that neither the character L ('\u004C') nor l ('\u006C') 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:

s - a String containing the long representation to be parsed

Returns:

the long represented by the argument in decimal.

Throws:

NumberFormatException - if the string does not contain a parsable long.

See Also:

Long.parseLong(String)

toDouble

public static double toDouble(String s)

Returns a new double initialized to the value represented by the specified String, as performed by the valueOf method of class Double.

Parameters:

s - the string to be parsed.

Returns:

the double value represented by the string argument.

Throws:

NumberFormatException - if the string does not contain a parsable double.

See Also:

Double.parseDouble(String)

toBool

public static boolean toBool(String s)

Returns a Boolean with a value represented by the specified string. The Boolean returned represents a true value if the string argument is not null and is equal, ignoring case, to the string "true".

Parameters:

s - a string.

Returns:

the Boolean value represented by the string.

See Also:

Boolean.parseBoolean(String)

toBigDecimal

public static BigDecimal toBigDecimal(String s)

Translates the string representation of a BigDecimal into a BigDecimal. The string representation consists of an optional sign, '+' ( '\u002B') or '-' ('\u002D'), followed by a sequence of zero or more decimal digits ("the integer"), optionally followed by a fraction, optionally followed by an exponent.

toList

public static List<String> toList(String s)

Convert a comma separated value string into a List.

Parameters:

s - a list with comma separated values

Returns:

a list with the trimmed values
