How to read password in console in Java?

The following illustrates reading password in console in Java which means that password isn't visible when the user is typing.

class ReadPassword
{
    public static void main(String args[])
    {
        System.out.println("Enter password");
       
        char[] c=System.console().readPassword();
       
        // Just print, make it simple
        System.out.println("The password is "+new String(c));
       
    }
}
System.console().readPassword(): The console() method generates a Console object which contains the readPassword() method. This method reads the password from the user into a char array and returns it.
