Today I'm searching for a way to mount a remote directory on my local machine, such that it acts like a local machine. The sole reason is to run the remotely compiled code locally.
I've found a nice article on it and would like to blog it here.
Here we go:

• Install SSHFS:

sudo apt-get install sshfs

• Add root to the fuse group: 

sudo adduser root fuse 

• Create the local backup director

mkdir backup

• Then mount the remote /home directory to backup:

sshfs -o idmap=user <username>@<remote system's ip>:/home backup

• Let's check if the remote directory got mounted to /backup:

mount

df -h

• To unmount the directory

fusermount -u backup

Check the backup folder to see your remote directory...

Sometimes we would like to save the output from console into a file and to do this we use some stream writer/reader to read from console and write to a file.

But this can be done in much easier way as follows. Add the following code at the beginning of the program:

PrintStream out = new PrintStream(new FileOutputStream("output.txt"));
System.setOut(out);

Now the default behaviour of out is changed to PrintStream out, and the output is redirected to the file provided above.

Edit:
To reset the standard behaviour, add the following code

System.setOut(stdout);
