What is the easiest way to iterate through the characters of a string in Java

Question

Please help.

Answer 1

The below code seems the easiest to me:

String str = "...abc...";

for (int i = 0; i < str.length(); i++)

{
    char c = str.charAt(i);        
}

Answer 2

There are two approaches to this:

for(int i = 0, n = s.length() ; i < n ; i++) {
    char c = s.charAt(i); }

or

for(char c : s.toCharArray()) {
    // process c}

The second approach is more readable while the first one is more faster.
