Question

Why are empty Strings valid and empty chars are not ?
I would have thought an empty String is not a string but just a placeholder. The same for a char, but creating an empty char does not even compile.

What im wondering is why the following occurs –
Compiles –

String s = "";

Does not compile –

char c = '';

Answer 1

Because char represents a single character, which '' isn’t. A String can contain zero or more characters, but a character cannot be anything other than a single character.
