1,313 PointsQuestion about getTileCount method
This is what I have so far but I'm really stuck.. Any help would be appreciated..
public int getTileCount(char tile) { int tileCount = 0; for(char count : mHand.toCharArray()){ tileCount += count; } return tileCount; }
public class ScrabblePlayer {
private String mHand;
public ScrabblePlayer() {
mHand = "";
}
public String getHand() {
return mHand;
}
public void addTile(char tile) {
// Adds the tile to the hand of the player
mHand += tile;
}
public boolean hasTile(char tile) {
return mHand.indexOf(tile) > -1;
}
public int getTileCount(char tile) {
int tileCount = 0;
for(char count : mHand.toCharArray()){
tileCount += count;
}
return tileCount;
}
}

71,830 PointsHere you go:
public int getTileCount(char ltr){
int mCount = 0;
int i = 0; //loop counter
for(char letter: mHand.toCharArray()){
//for (int i = 0; i < mHand.length(); i++) {
if(mHand.charAt(i) == ltr){
mCount++;
}
i++;
}
return mCount;
}
Since you need subscript notation to access the elements in the array, you would need to create a loop counter variable, use it, and increment it each time through the loop.

71,830 PointsSteve, here's the function. The key thing here is that you have to compare the letter/tile passed into the function with each letter/tile in mHand.
public int getTileCount(char ltr){
int mCount = 0;
for (int i = 0; i < mHand.length(); i++) {
if(mHand.charAt(i) == ltr){
mCount++;
}
}
return mCount;
}
But just in case, here's the whole thing:
import java.util.*;
public class ScrabblePlayer {
private String mHand;
public int getTileCount(char ltr){
int mCount = 0;
for (int i = 0; i < mHand.length(); i++) {
if(mHand.charAt(i) == ltr){
mCount++;
}
}
return mCount;
}
public ScrabblePlayer() {
mHand = "";
}
public String getHand() {
return mHand;
}
public void addTile(char tile) {
// Adds the tile to the hand of the player
mHand += tile;
}
public boolean hasTile(char tile) {
return mHand.indexOf(tile) > -1;
}
List<String> list = new ArrayList<String>();
}

1,313 PointsThanks so much! Is there a way to write this with a for-each loop?
