Get file from the specified path

I need to read a file from a specified path. E.g: I have a file called abc.txt and it resides inside /dev/user/assets/data/abc.png. If one has to read from a Zip file we do something like

Zipfile zipFile = new ZipFile("test.zip");
ZipEntry entry = zipFile.getEntry(imagePath); // where image path is /dev/user/assets/data/abc.png.

Is there a code something similar to the above for reading from a folder? Like 

File folder = new Folder("Users");

and give the path "/dev/user/assets/data/abc.png" to the above and read the image.

I'm not sure if I understand exactly what you want to do. But if what you want to do is simply to read the contents of a file with a given path, then you should'nt use the File API.

Instead you should use a new FileReader(textFilePath); or a new FileInputStream(imageFilePath);

Look at the following example, taken from the java tutorials.

import java.io.FileReader;
import java.io.FileWriter;
import java.io.BufferedReader;
import java.io.PrintWriter;
import java.io.IOException;

public class CopyLines {
    public static void main(String[] args) throws IOException {

        BufferedReader inputStream = null;
        PrintWriter outputStream = null;

        try {
            inputStream = new BufferedReader(new FileReader("xanadu.txt"));
            outputStream = new PrintWriter(new FileWriter("characteroutput.txt"));

            String l;
            while ((l = inputStream.readLine()) != null) {
                outputStream.println(l);
            }
        } finally {
            if (inputStream != null) {
                inputStream.close();
            }
            if (outputStream != null) {
                outputStream.close();
            }
        }
    }
}

Yes, File has two-args constructor File(File parent, String child) that does exactly what you describe (you may just have to throw the leading '/' of the child). Take a look at the JavaDoc
