netbean,why is my write is unexpected?

Question

so im making a hangman game and im having a "expected type required:variable found:value", error please help.

the mistake is similar to this mistake:
String w1="abc",w2="cba";
w1.charAt(0)=w2.charAt(0);

Answer 1

The charAt() function returns a character. You might wanna use some other function to replace that character with a new one.

w1 = w1.replace(w1.charAt(0), w2.charAt(0));
