InputStream from relative path
JavaPathIoInputstreamRelative PathJava Problem Overview
I have a relative file path (for example "/res/example.xls") and I would like to get an InputStream Object of that file from that path.
I checked the JavaDoc
and did not find a constructor or method to get such an InputStream from a path/
Anyone has any idea? Please let me know!
Java Solutions
Solution 1 - Java
Use FileInputStream
:
InputStream is = new FileInputStream("/res/example.xls");
But never read from raw file input stream as this is terribly slow. Wrap it with buffering decorator first:
new BufferedInputStream(is);
BTW leading slash means that the path is absolute, not relative.
Solution 2 - Java
InputStream inputStream = Files.newInputStream(Path);
Solution 3 - Java
Initialize a variable like: Path filePath
, and then:
FileInputStream fileStream;
try {
fileStream = new FileInputStream(filePath.toFile());
} catch (Exception e) {
throw new RuntimeException(e);
}
Done ! Using Path you can have access to many useful methods.
Solution 4 - Java
new FileInputStream("your_relative_path")
will be relative to the current working directory.
