8,401 Pointsbad initializer for for-loo
Why doesnt this code work, it keeps saying: 'bad initializer for for-loop'. Can you explain the reason to me?
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 counter = 0;
for(tile : mHand.toCharArray())
{
if(mHand.indexOf(tile) > 0){
counter++;
}
}
return counter;
}
}

The problem is that you used tile from the getTileCount parameter list as the name for the first variable in the for each loop. Instead, consider declaring a new variable inside of the loop:
public int getTileCount( char tile ) {
int count = 0;
for ( char letter : mHand.toCharArray() ) {
if ( letter == tile ) {
count++;
}
}
return count;
}

3,153 Pointsthank you for the answer I was having the same problem. Can any one explain how the for-loop knows what char it is searching when the values are different in getTileCount( ) and the for( ). Also why his original code was not excepted. I'm very new to java but in my experience his original should have worked.
