Answer 1

Look at System.out.println for prompting the user and displaying the welcome message (assuming you do not have to use a GUI). Look at Scanner(System.in) or the Console class to read the password. Use an "if" statement to check if the password .equals the expected password (assuming it is not held in some sort of database/file).

Hello,

if i understand your question it is more about *nix passwords and logins. Have a look at the /etc/passwd and /etc/shadow files and research about how the passwords are hashed. Once you understand that you may write a java program to hash the input password and compare it with the content of /etc/shadow...

Have a look at Shadow_password
