     System.out.print("Nice to meet ya, " + name + "! :)");
}

public static Scanner exampleMethod(String default1, int default2) {

4. I want to write a method that will translate an English word into an Arabic word. I will pass the method a word in English and it will search through a big array of English words until it finds the same word. It will take note of the index number, then look up the same index number in a big array of Arabic words, which will produce the translation of the word into Arabic. The method will then return the translated Arabic word. How many parameters should I have?
    A.     0
    B.     1
    C.     2
    D.     3
    E.     None of these choices, because you can't write a method to do this.
