Length of the String without using length() method [closed]
How can I find the length of a String without using the length() method of String class?
str.toCharArray().lengthshould work.-
Or how about:
str.lastIndexOf("")Probably even runs in constant time :)

Another one
Matcher m = Pattern.compile("$").matcher(str); m.find(); int length = m.end(); One of the dumbest solutions:
str.split("").length - 1Is this cheating:
new StringBuilder(str).length()? :-)
String blah = "HellO";
int count = 0;
for (char c : blah.toCharArray()) {
count++;
}
System.out.println("blah's length: " + count);
