To do: add code to Ex5BaseballPlayers to complete the comments in the code.

import java.util.ArrayList;

public class Ex5BaseballPlayers

//-----------------------------------------------------------------

// Stores and modifies a list of baseball players.

//-----------------------------------------------------------------

// NOte: We could (and probably should) create a Player blueprint

// and use that. But in this case, I just want an array list

// of Strings.

public static void main (String[] args)

{

// always make your array lists generic

ArrayList players = new ArrayList();

players.add("Albert Pujols");

players.add ("Aaron Judge");

// You could use the following to print out all of the players

// since Java will call the toString() on each individual item if you do not

// but it is better to do it explicitly yourself

//System.out.println (players);

System.out.println("The baseball players are: ");

for (int i=0;i

System.out.println(players.get(i).toString());

// Note the line above---if this was anything but Strings in the array list

// it would work the same way but I would explicitly call the toString() method.

// Now let's remove Anthony Rizzo

int location = players.indexOf ("Anthony Rizzo");

players.remove(location);

// could do it in one step: players.remove (players.indexOf ("Anthony Rizzo"));

// Prove that it worked by printing the information out

System.out.println(" Without Anthony:");

for (int i=0;i

System.out.println(players.get(i));

// Find out who is the third one on the list (remember that we start counting at zero

System.out.println (" The third player in the list now is " + players.get(2));

// Add in Zack Greinke as the fourth player

players.add (3, "Zack Greinke");

//Print these out

System.out.println(" With Zack added as the fourth player we now have:");

for (int i=0;i

System.out.println(players.get(i));

// print out how many players there are

System.out.println(" The number of players is now "+ players.size());

//YOU DO THE FOLLOWING. FIND METHODS FOR THESE!!

// check to see if Adrian Gonzalez is on the player list. It should print true or false.

// find out the index for the location of Jose Altuve

// find the indexes for Mike Trout. There is no single method to do this.

// Loop through the array list. Use the method .equals to compare the entry to "Mike Trout"

// print out the index number if it is equal.

// NOTE: For Strings you cannot use == (this can only be used for primitive data types)

// for objects == checks to see if it is the same object ---not that the contents are the same

// find all of the players whose first names start with the letter J.

// Print these. HINT!!! There is

// no single method for this. You will need to loop through the ArrayList getting

// each entry and checking to see if the string starts with an J.

// find a way to print out the list of the LAST names of the players. (Hint: I would use substrings or the String split method)

// print out the list of all of the players but all of the letters in all of the names

// need to be capitalized.

// clear out all the members of the ArrayList

// print out the ArrayList now and the size now.
