6,744 PointshasTile method error. When I run the program there is a compiler error in my hasTile method
I think i may be calling the "IndexOf" method wrongly? Any help would be greatly appreciated! Thanks.
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) {
boolean verdict;
if(mHand.IndexOf(tile) >= 0) {
verdict = true;
}
else {
verdict = false;
}
return verdict;
}
}

57,712 PointsHi there,
You're not far off at all. Lose the capital i at the start of indexOf
. It is lower case. And that's it; your code will now pass. However, the code can be simplified.
My solution looked like:
public boolean hasTile(char tile) {
if(mHand.indexOf(tile) >= 0) {
return true;
} else {
return false;
}
}
which does exactly the same thing without using an interim boolean variable. But that can be simplified still further with this:
public boolean hasTile(char tile) {
return mHand.indexOf(tile) >= 0
}
The mHand
expression can only result in a true
or false
answer. The if
statement adds some clarity, perhaps, but it isn't needed.
I hope that helps.
Steve.
