Hello, in my main method I have multiple questions which should be answer with one letter, but if the user enters capital, the program should lowercase it. So in the code below I described my problem and I was wondering if I should name each letter or if I should do something else

What I have tried:

char lowerCase='C'='U'='F'='D'='K'='P';
 lowerCase = toLowerCase(lowerCase);

This method transforms the letters into lowercase letters
public static char toLowerCase(char lowerCase){
   if (lowerCase >= 'A' && lowerCase <= 'Z')
       lowerCase = (char) (lowerCase + 32);
    return (lowerCase);

Yes, read the Java documentation for String and Character types.

Um. You do realize ... Java - String toLowerCase() and toUpperCase() Methods[^] exist already?
