If display already has a value of "-",how is it it/or I can change its value to letter. It doesnt make any sense ???

public String getCurrentProgress(){ String progress = ""; for(char letter : answer.toCharArray()){ char display = '-'; if(hits.indexOf(letter) != -1){ display = letter; } progress += display; } return progress; }

Hi there! So when we initially are declaring the variable 

char display = '-';

This declares a variable that holds a character, named display. We just put in a placeholder of "-" inside of the variable to be used by default. Because this is a variable though we can change its value at anytime. The next line down we could say

display = 'A';

And this would set the display variable to A.

In the context of this code, we are running a for loop to check each individual letter in the answer string to see if there is a match

    for(char letter : answer.toCharArray()){

If there is a match, we are able to take the current letter (letter variable), and assign it directly to the display variable in order to show that letter.

Hope that helps, take care and happy coding !
