Java FileNotFoundException even though file exists

I am trying to read a file located at "C:\Users\Siddharth\Documents\aarti\yeh_vidhi_mangal.txt". Following code indicates that file exists

String filename = "C:\\Users\\Siddharth\\Documents\\aarti\\yeh_vidhi_mangal.txt";
        File file = new File(filename);
        System.out.println(file.exists());

but when I try to open the file using

FileInputStream in = new FileInputStream(file);

a FileNotFoundException is thrown. Is this because access is denied? I checked file permissions and they are fine.

I have also tried working without eclipse. from the command line: 

 C:\Users\Siddharth\workspace\file_io_test\src>javac Foo.java
    Foo.java:16: error: unreported exception FileNotFoundException; must be caught o
    r declared to be thrown
                    FileInputStream in = new FileInputStream(file);
                                         ^
    1 error

Try using single slash rather than double slash like

C:/User/Documents/your Filename.

and use Backward Slash Because your File is going to inherit in the following Directories so write the path like this for ex:

C:\User\Documents\Your Filename.

According to the documentation for FileInputStream, "If the named file does not exist, is a directory rather than a regular file, or for some other reason cannot be opened for reading then a FileNotFoundException is thrown." (emphasis mine) The file may be locked or in use by another application.

What does file.canRead() return?

Now that you've updated your question with more data, I can see that you are misinterpreting the error message. The error is that you are calling a method which throws a certain type of exception and you are not properly reporting or handling the exception. You can either add a try / catch for FileNotFoundException or add a throws to your method declaration which states that FileNotFoundException can be thrown.
