仅获取路径目录并丢弃Java中的文件 [英] Get path directory only and discard file in Java

问题描述

我们如何实际上丢弃Java字符串中的最后一个文件并仅获取文件路径目录?

How do we actually discard last file from java string and just get the file path directory?

用户输入的随机路径:

C:/my folder/tree/apple.exe

所需的输出:

C:/my folder/tree/

我发现的

最近的解决方案来自此处 .该论坛的答案仅显示最后获取的字符串，而不显示其余字符串.我想显示字符串的其余部分.

closest solution i found is from here . The answer from this forum only display last string acquired not the rest of it. I want to display the rest of the string.

推荐答案

最简单，最具故障保护性(跨平台)的解决方案是从路径创建File对象.

The easiest and most failsafe (read: cross-platform) solution is to create a File object from the path.

赞:

File myFile = new File( "C:/my folder/tree/apple.exe" );
// Now get the path
String myDir = myFile.getParent();
