Method Detail

parseBoolean

public static boolean parseBoolean(String s,
                                   boolean d)

Turns a string into a boolean value and returns a default value if unsuccessful.

Parameters:

s - the string to convert

d - the default value

Returns:

equivalent boolean value

parseInt

public static int parseInt(String s,
                           int def)

Turns a string into an int and returns a default value if unsuccessful.

Parameters:

s - the string to convert

def - the default value

Returns:

the int value

parseIntRadix

public static Number parseIntRadix(String s,
                                   int radix)

Turns a string into an int using a given radix.

Parameters:

s - the string to convert

radix - radix to use

Returns:

the int value

parseInt

public static int parseInt(String s,
                           int def,
                           int[] lastIdx,
                           boolean allowNegative)

Turns a string into an int and returns a default value if unsuccessful.

Parameters:

s - the string to convert

def - the default value

lastIdx - sets lastIdx[0] to the index of the last digit

allowNegative - if negative numbers are valid

Returns:

the int value

parseNumber

public static Number parseNumber(String s,
                                 Number def)

Turns a string into a Number and returns a default value if unsuccessful.

Parameters:

s - the string to convert

def - the default value

Returns:

the numeric value

parseStrict

public static Number parseStrict(String s)

Use Java's "strict parsing" methods Integer.parseInt and Double.parseDouble to parse s "strictly". i.e. if it's neither a double or an integer, fail.

Parameters:

s - the string to convert

Returns:

the numeric value

parseIfInt

public static int parseIfInt(String s,
                             int def)
