parse

public BigDecimal parse(String text,
                        Locale locale)
                 throws ParseException

Parse a text String to produce a T.

指定者:

parse 在接口中 Parser<Number>

覆盖:

parse 在类中 AbstractNumberFormatter

参数:

text - the text string

locale - the current user locale

返回:

an instance of T

抛出:

ParseException - when a parse exception occurs in a java.text parsing library

getNumberFormat

protected NumberFormat getNumberFormat(Locale locale)

从类复制的说明: AbstractNumberFormatter

Obtain a concrete NumberFormat for the specified locale.

指定者:

getNumberFormat 在类中 AbstractNumberFormatter

参数:

locale - the current locale

返回:

the NumberFormat instance (never null)
