Practice for my AP Computer Science students interested in making more efficient code

Improve this code

     * Help! I used too many lines of code. Help me make this more efficient.
     * This main method must create an array with the same words shown below. Then I
     * have to test each word with this validatePassword method. If the password is valid, 
     * I have to print a message. Can you make this more efficient?
