4,751 PointsPassing char and adding to mHand field.
Error is unexpected return value pointing at i on is Tile.
If I remove return isTile, error is return value or something is expected
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
boolean isTile = mHand.indexOf(tile) >= 0;
if(isTile){
mHand += tile;
}
return isTile;
}
public boolean hasTile(char tile) {
return false;
}
}

public void addTile() {
...
return isTile;
}
Either change your method declaration (to boolean) or return null.

1,188 PointsI think I just had your same question, here was my solution.
<p>
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 isTile = mHand.indexOf(tile) >= 0;
if (isTile) {
return true;
} else {
return false;
}
}
</p>
Notice that you had the right idea, but were unsure what method to put it in. Side note, I think void methods might not need return lines. Also, I would like to hear someone explain void methods and return types if they have a chance. Thanks!

4,751 Points@Tom Sager i did that but I am being compeled to use += method to add chars to existing string. below is my code. @TJ note I should use the += method
public boolean addTile(char tile) { // Adds the tile to the hand of the player boolean isTile = mHand.indexOf(tile) >= 1; if (isTile) { mHand += tile; } return isTile;
