LocalDate類parse()方法 (LocalDate Class parse() method)

Syntax:

句法：

public static LocalDate parse(CharSequence c_seq); public static LocalDate parse(CharSequence c_seq, DateTimeFormatter fmtr);

• parse() method is available in java.time package.

  parse()方法在java.time包中可用。

• parse(CharSequence c_seq) method is used to create an instance of LocalDate from parsing the given char sequence.

  parse(CharSequence c_seq)方法用于通過(guò)解析給定的char序列來(lái)創(chuàng)建LocalDate的實(shí)例。

• parse(CharSequence c_seq, DateTimeFormatter fmtr) method is used to create an instance of LocalDate from parsing the given char sequence based on the given formatter.

  parse(CharSequence c_seq，DateTimeFormatter fmtr)方法用于根據(jù)給定的格式器解析給定的char序列來(lái)創(chuàng)建LocalDate的實(shí)例。

• These methods may throw an exception at the time of the represent date.

  這些方法在表示日期時(shí)可能會(huì)引發(fā)異常。

  DateTimeParseException: This exception may throw when the given parameter can't parse.

  DateTimeParseException：當(dāng)給定參數(shù)無(wú)法解析時(shí)，可能引發(fā)此異常。

• These are static methods and it is accessible with the class name and if we try to access these methods with the class object then we will not get an error.

  這些是靜態(tài)方法，可通過(guò)類名進(jìn)行訪問(wèn)，如果嘗試使用類對(duì)象訪問(wèn)這些方法，則不會(huì)出錯(cuò)。

Parameter(s):

參數(shù)：

• In the first cases, parse(CharSequence c_seq),

  在第一種情況下，parse(CharSequence c_seq)

  • CharSequence c_seq – represents the sequence to parse in this object.
  • CharSequence c_seq –表示要在此對(duì)象中解析的序列。

• In the second cases, parse(CharSequence c_seq, DateTimeFormatter fmtr),

  在第二種情況下，解析(CharSequence c_seq，DateTimeFormatter fmtr)，

  • CharSequence c_seq – Similar as defined in the first case.
  • CharSequence c_seq –與第一種情況下定義的相似。
  • DateTimeFormatter fmtr – represents the formatter to format the sequence in this object.
  • DateTimeFormatter fmtr –表示格式化程序，用于格式化此對(duì)象中的序列。

Return value:

返回值：

In both the cases, the return type of the method is LocalDate, it returns the date that holds the value parsed the given sequence in a formatted manner.

在這兩種情況下，方法的返回類型均為L(zhǎng)ocalDate ，它以格式化的方式返回保存解析給定序列的值的日期。

Example:

例：

// Java program to demonstrate the example // of parse() method of LocalDateimport java.time.*; import java.time.format.*;public class ParseOfLocalDate {public static void main(String args[]) {CharSequence c_seq = "2005-06-05";DateTimeFormatter dtf = DateTimeFormatter.ofPattern("dd-MMM-yyyy");// Here, parse(CharSequence) create an// instance of LocalDate from a// CharSequenceLocalDate l_da = LocalDate.parse(c_seq);// Display l_daSystem.out.println("LocalDate.parse(c_seq): " + l_da);// Here, parse(CharSequence,DateTimeFormatter)// creates an instance of LocalDate from a // CharSequence by using the given// DateTimeFormatterl_da = LocalDate.parse("15-Aug-1991", dtf);// Display l_daSystem.out.println("LocalDate.parse(15-Aug-1991,dtf): " + l_da.toString());} }

Output

輸出量

LocalDate.parse(c_seq): 2005-06-05 LocalDate.parse(15-Aug-1991,dtf): 1991-08-15
