963 PointsStuck on task 2 of 2 Scrabble counting tiles
I'm so lost and I can't continue
public class ScrabblePlayer {
// A String representing all of the tiles that this player has
private String tiles;
public ScrabblePlayer() {
tiles = "";
}
public String getTiles() {
return tiles;
}
public void addTile(char tile) {
tiles += tile;
}
public boolean hasTile(char tile) {
return tiles.indexOf(tile) != -1;
}
public int a (char letter) {
int getCountOfTile = 0;
int countOfTiles = 0;
for (char x : tiles.toCharArray()){
if (tiles.charAt(x) != -1){
countOfTiles ++; }
countOfTiles == getCountOfTiles;
}
} }

Task 1 hasn't been completed here. For that you need to Create a new method named getCountOfLetter that returns an int, and requires a parameter of type char named letter.
So, you need a public method that returns an int called getCountOfLetter which takes a char called letter. Put that code all together and you get:
public int getCountOfLetter(char letter){
return 0;
}
Next, Now in your new method, have it return a number representing the count of tiles that match the letter that was passed in to the method. You've made a good start on this as you've identified that you need a for loop and to convert tiles into toCharArray(). That loops through each letter, storing each in x at each iteration. You want to compare that x to the letter passed in. if they are equal, increment a counter variable. Again, you've done that. Return the counter variable after the loop ends.
Your test isn't quite right because you've tried to compare to -1. That's an indicator that the character is in the string/array, rather than being at that position. You tried tiles.charAt(x). Unfortunately, x is a char, not an index number but it was a good effort.
Just use double equals to compare x to letter.
To simplify your code, you'll end up with:
public int getCountOfLetter(char letter){
int count = 0;
for(char l : tiles.toCharArray()){
if(l == letter){
count++;
}
}
return count;
}
I hope that makes sense.

57,712 PointsI called the
charthe letterl(it isn't the figure 1) as the wordletterhas already been used. I could have called it anything but, since it represents a single character, I used a one-letter variable name. Hadletternot already been taken, I'd have used that.Looking back, I should have used
tilerather thanl. That makes more grammatical sense.It can be called anything - but using something relevant is easier to read. So a single character for a
charor the singular version of the array name is sensible.But it isn't, and nor can it be, a number - you can't start a variable name with a number.
Make sense?
