How do I Write a Java Program That prompts the user to enter a password and displays it back in the console window. The displayed password should be the entered password halved with the full password total number of characters added at the end.
example1:
enter your password: abcd
your password is : ab4

example2:
enter your password: abcde
your password is :ab5

Note: always assume that the user will enter a password with at least two characters. Additionally, you don’t need to consider the cases if the password length is an odd number (e.g: if the password length is 5 the program should only display the first two characters along with the full length).

Thank you sir!
