    Default Arrays

    I am writing a public instance method called writeCharacter() which takes a single argument
    of type char called aCharacter and returns no result. The method invokes the getCharacter() method
    on the DisplayFont class with aCharacter as its argument. The getCharacter() returns a two-dimensional
    array of type boolean which has x and y dimensions.
    I would like to assign the array to a local variable called alpha.

    The question is how do I code this with correct syntax into my method writeCharacter(char aCharacter)

    /* instance method */
    	public void writeCharacter(char aCharacter)

    Thanks a million,

    Simply declare the array and assign the return result of getCharacter to that variable. There's no need to pre-determine the dimensions (that's determined by getCharacter when it first allocated the array).

    public void writeCharacter(char aCharacter)
         boolean alpha[][] = DisplayFont.getCharacter(aCharacter);

    Have you tried anything yet?
    Can you post the declaration for the getCharacter() method?
    Define a two dimension array:
    <type>[][] twoDim; // define a two dimensional array of type <type> (replace <type> with the type
    Then you can assign what is returned by getCharacter() to the twoDim variable.
