Then, the first element of the ArrayList will be the minimum value and the last element of the ArrayList will be the maximum value. Linux/Unix/equivalent: edit the 'bluej' shell script which is created by the installer (in the directory where you installed BlueJ), and modify the last line (which launches BlueJ). Sort it using the sort() method of the Collections class.
To get minimum and maximum values of an ArrayList − Last element of the array list: Impala Example 2 ("Last element of the array list: "+list.get(list.size()-1))
#ARRAYLIST BLUEJ CODE#
2) I'm stepping through your code snippet of makeDeckFull (), and it seems to work fine. As is, you are printing out the reference of the object (the gibberish) instead of the 'data.' You should also override the toString () method of Deck to only print out the list.
("First element of the array list: "+list.get(0)) 1) You need to override toString () in the Cards class.
Therefore, if you pass 0 to this method you can get the first element of the current ArrayList and, if you pass list.size()-1 you can get the last element. The syntax is also slightly different: Example. The get() method of the ArrayList class accepts an integer representing the index value and, returns the element of the current ArrayList object at the specified index. Use BlueJ to create methods that do the following: Print an ArrayList of.
