Java OCA OCP Practice Question 2056

Question

Given the following program:. 

import java.io.Console;

public class Main {

 public static void main(String[] args){
   Console console = System.console();
   if (console == null) {
     System.err.println("No console available.");
     return;// w w  w . j a  va2s .c om
   }
   String username = console.readLine("Enter user name (%d chars): ", 4);
   char[] password = console.readPassword("Enter password (%d chars): ", 4);

   System.out.println("Username: " + username);
    System.out.println("Password: " + String.valueOf(password));
  }
}

Assume that the user types the strings java aaaa and bbbb cccc when prompted for the user name and the password, respectively.

Which statement about the program is true?.

Select the one correct answer. 

(a)  The program will print:/* w  w w .  j  a va  2  s  .  c o m*/
     Username: java
     Password: bbbb cccc
(b)  The program will print:
     Username: java aaaa
     Password: bbbb
(c)  The program will print:
     Username: java aaaa
     Password: bbbb cccc
(d)  The program will print:
     Username: java
     Password: bbbb



(c)

Note

Both the readLine() and the readPassword() method of the Console class return all characters typed on the line.

The arguments of the two methods concern the prompt written to the console.
