Everything inside the ' ' is considered a char in java. So you can write . char a = '/'; char b = '#'; The difference between char and String is that char is only and always one character (letter or symbol). But String can be zero or more characters. Also char is a primitive type. String is a class. You can think of char like a letter and String like a word (a collection of letters or an array of chars if you like more).

Thx Nedim! Is it # and / consider as char also? I see the book write like : showLine('#'); and showLine('/', 20);

single quotes are for chars, double quotes are for Strings, example: char c = 'a'; String s = "hello";
