Question

I need to check if a character is an apostrophe. This is my code so far:

public boolean isWordCharacter(int c) {
if ((char) c == '\'')
    return true;
else return Character.isLetter(c);
}

However, it never actually gets into the if ((char) c == '\'') part. Is there something wrong with the way I check it? Thanks!

Answer 1

You could simply use if(c=='\'') without cast. Or you can use ascii value of apostrophe which is 39. if (c==39) will do.

it never actually gets into the ‘if ((char) c == ‘\”) part

The only reason for this could you never pass apostrophe to isWordCharacter(). You can verify it by manually sending 39 or '\'' to that function.
