Dictionary.txt is a file that has about 60,000 words. one per line.

I also have no idea what to do for step 1 in boggle.java

Tasks and Rubric

Activity
Boggle project
boggle package
Boggle.java	Set the ArrayList member variable that stores the Boggle data equal to method call shakeDice in class Board
core package
Board class	Add member variable of class ArrayList specifically using class String as the data type for the ArrayList to store the game data Generate a getter for the game data member variable Implement method shakeDice to do the following:Loop through the 16 dice Randomly select 1 of the 16 dice Call method rollDie in class Die Store the returned value in the ArrayList created above for the game data Be sure to use each die only once, you will have to keep track of which die was used Implement a method that will loop through the ArrayList of game data and display the board to the output window of the IDE (see figure 2)
Die class	Implement method rollDie to do the following: Randomly select one of the six letters of the die that will be used as the game data Return that value
Boggle application
Test Case 1	Test Case 1 passes
Test Case 2	Test Case 2 passes
	Source compiles with no errors
	Source runs with no errors
	Source includes comments
Total

Perform the following test cases

Test Cases
	Action	Expected outcome
Test Case 1	Project view	Completed project view should look like figure 1
Test case 2	Run application	shakeDice output should be similar to figure 2

Figure 1: Output from method displayGameData()
