I need help completing this program the right way please help

1. Your program must have an array of words (Strings) from which one of the words is randomly chosen to play a round of the game. Please don’t include more that 5 words so that I can easily test your program:
String [ ] words = { “javascript”, “declaration”, “object”, “class”, “failing” };
2. Your program must contain at least one character array such as:
char [ ] alphabet;
3. Your program must contain at least 3 method definitions not including the main method definition.
4. One of the method definitions must be a method called: explode
The explode method is sent a string such as: “javascript” and returns an array of characters containing the letters that appear in the words: ‘j’ ‘a’ ‘v’ ‘a’ ‘s’ ‘c’ ‘r’ ‘I’ ‘p’ ‘t’

this is what i have so far

but i also cant get the little man to form when you start guessing and i dont know if im missing something.
