Question

Here’s what I’ve got:

private static int countNumChars(String s) {
    for(char c : s.toCharArray()){
        if (Equals(c," "))
    }
}

But that code says it cannot find Symbol for that method. I remember Java having a comparer like this… Any suggestions?

Answer 1

if (c == ' ')

char is a primitive data type, so it can be compared with ==.

Also, by using double quotes you create String constant (" "), while with single quotes it’s a char constant (' ').
