如何获取日期图片创建在java [英] How to get date picture created in java

问题描述

我想提取创建jpg文件的日期。 Java具有File对象的lastModified方法，但似乎不支持从文件中提取创建的日期。我相信信息存储在文件中，当我在Win XP中将鼠标指针悬停在文件上时，我看到的日期与使用DOS中的文件上的dir / TC使用JNI可以得到的不同。 p>

I would like to extract the date a jpg file was created. Java has the lastModified method for the File object, but appears to provide no support for extracting the created date from the file. I believe the information is stored within the file as the date I see when I hover the mouse pointer over the file in Win XP is different than what I can get by using JNI with "dir /TC" on the file in DOS.
