parseFloatDimension

public static FloatDimension parseFloatDimension(String floatDimension)
                                          throws NumberFormatException

Creates a FloatDimension object based on a given string.

The given string consists of two floating-point numbers (either positive or negative) separated by an asterisk (*) (ASCII 0x2A) in the format of W*H, for example, 8.5*10.2 or -6.3*-8.4.

参数:

floatDimension - Indicates the string used to create the FloatDimension object.

返回:

Returns a FloatDimension object.

抛出:

NullPointerException - Throws this exception if floatDimension is null.

NumberFormatException - Throws this exception if the specified string is illegal.
