1. Frogs and Toads 4 FrogApp and FrogApplet

2. Some updates Frogs and Toads 3 (after) has partial functionality
can move an amphibian
can determine if frog move (one square) is legal
need to check if hops move is legal
need to do Toads as well

3. FrogGame class validMove method
checks the status of a pad to see if FROG or TOAD
we used gameBoard.getPad(row,column).getStatus()
when checking for hops
have to check neighbor square is opposite type
could go "off the board" – outside legal limits for row/col
will cause run time error (red messages!)
Instead use gameBoard.statusOfPad(row,column);
this method will have protection inside
checks for illegal row/column values

4. FrogGame class int StatusOfPad(row,column)
if the row is <0 OR >= size
return Pad.INVALID
same deal with col
otherwise, return gameBoard.getPad(row,column).getStatus();

5. Pond class The toString method provided draws board upside down
low rows on top.
Opposite of the example games
We can easily flip the board, see method and verify in FrogGameTester

6. FrogApp class comments and pseudocode provided
very easy once you get the FrogGame class working

7. FrogApplet class starter code provided
we'll do the board drawing together
and also how to convert mouse clicks to row/col values
