Java is dumb

Can someone tell me how I can turn a string like "http://www.google.com/" and return the protocol "http" by returning all characters before "://"? I tried using split but that gives me an array but we haven't even covered arrays yet so somehow I think I must be on the wrong track.

All I want is a god damn sub string using a string as the parameter

:<

I would do

String s = "http://www.google.com/";
String prot = "";
for (int i = 0; i + 2 < s.length(); i++) {
   if (s.charAt(i) == ':' && s.charAt(i + 1) == '/' && s.charAt(i + 2) == '/') {
      prot = s.subString(0,i);
      break;
   }
}

I would do

String s = "http://www.google.com/";
String prot = "";
for (int i = 0; i + 2 < s.length(); i++) {
   if (s.charAt(i) == ':' && s.charAt(i + 1) == '/' && s.charAt(i + 2) == '/') {
      prot = s.subString(0,i);
      break;
   }
}

Sorry for double post. Also, the line

prot = s.subString(0,i);

should be

prot = s.substring(0,i);

No clue why only this function doesn't follow java naming conventions.

String s = "http://www.google.com/";
String prot = s.split("://")[0];
