2D array to draw a letter 'F'
I can't imagine any good reason for drawing an F using that approach.  Drawbacks include:


It is not obvious at all, just from looking at the code, what the expected output is.
Not only is the code hard to read, it is also hard to write and modify.
Using many small System.out.print() calls is very inefficient.


A solution like this, for example, is much easier to understand.  It would also be more efficient, since all of the output is done in one System.out.print() call.

public static final String F =
    "*****\n" +
    "*    \n" +
    "*****\n" +
    "*    \n" +
    "*    \n";

public static void main(String[] args) {
    // Print with 2x magnification
    System.out.print(F.replace("*", " *").replace("\n", "\n\n"));
}
