OpenSSH : SSH File Transfer (CentOS)

 [1]. It's the exmaple for using SCP (Secure Copy).

# command ⇒ scp [Option] Source Target
# copy the [test.txt] on localhost to remote host [node01.srv.world]

[cent@dlp ~]$ scp ./test.txt cent@node01.srv.world:~/

cent@node01.srv.world's password:   # password of the user

test.txt                                      100%   10     0.0KB/s   00:00

# copy the [/home/cent/test.txt] on remote host [node01.srv.world] to the localhost

[cent@dlp ~]$ scp cent@node01.srv.world:/home/cent/test.txt ./test.txt

cent@node01.srv.world's password:

test.txt                                      100%   10     0.0KB/s   00:00

[2]. It's the examples to use SFTP (SSH File Transfer Protocol). SFTP server feature is enabled by default, but if not, enable it to add the line [Subsystem sftp /usr/libexec/openssh/sftp-server] in [/etc/ssh/sshd_config].

 # sftp [Option] [user@host]

[redhat@dlp ~]$ sftp cent@node01.srv.world

cent@node01.srv.world's password:   # password of the user

Connected to prox.srv.world.

Java : Variables Declaring

[1]. Java Variables Variables are containers for storing data values. In Java, there are different types of variables, for example: String - stores text, such as "Hello". String values are surrounded by double quotes int - stores integers (whole numbers), without decimals, such as 123 or -123 float - stores floating point numbers, with decimals, such as 19.99 or -19.99 char - stores single characters, such as 'a' or 'B'. Char values are surrounded by single quotes boolean - stores values with two states: true or false [2]. Declaring (Creating) Variables To create a variable, you must specify the type and assign it a value: Syntax type variable = value ; Where type is one of Java's types (such as int or String), and variable is the name of the variable (such as x or name).
