indexof

There are plenty of solutions on how to get the indexOf implementation into the Array prototype so that it works under Internet Explorer, however I've stumbled upon an issue that doesn't seem to be addressed anywhere I've looked so far. Using the pretty well agreed upon implementation at MDC , I have the following code that's being problematic now: // indexOf support for IE (from MDC) if (!Array.prototype.indexOf) { Array.prototype.indexOf = function(elt /*, from*/) { var len = this.length >>> 0; var from = Number(arguments[1]) || 0; from = (from < 0) ? Math.ceil(from) : Math.floor(from); if

I'm trying to use indexOf to find all occurrences of the characters 'the' in a sentence. For example, if the sentence were "The other day I went over there", it should return 3. I am able to do this up to the point where it finds the first index, but I'm unsure of how to write the loop. I originally had a for loop that searched the entire string, but it was returning the full string character length, instead of the occurrences of my specified character. How can I write a loop that will find all of the occurrences of the word? Thank you. import java.util.Scanner; public class TheFinder { public

For example: str = "(a+b)*(c+d)*(e+f)" str.indexOf("(") = 0 str.lastIndexOf("(") = 12 How to get the index in second bracket? (c+d) <- this Try this : String word = "(a+b)*(c+d)*(e+f)"; String c = "("; for (int index = word.indexOf(c);index >= 0; index = word.indexOf(c, index + 1)) { System.out.println(index);//////here you will get all the index of "(" } wrm int first = str.indexOf("("); int next = str.indexOf("(", first+1); have a look at API Documentation You can use StringUtils from Apache Commons, in this case it would be StringUtils.indexof(str, ")", str.indexOf(")") + 1); The idea is

I have the following String myString="city(Denver) AND state(Colorado)"; It has repeating "(" and ")"... How can I retrieve state name, i.e. Colorado. I tried the following: String state = myString.substring(myString.indexOf("state(")+1,myString.indexOf(")")); But it give indexOutOfBoundException Is there any way to specify that I need the second "(" in myString? I need the result: String state = "Colorado"; Use lastIndexOf . Also increase the initial offset to allow for the number of characters in the sub-string state( : String state = myString.substring(myString.indexOf("state(") + 6,

I've written a custom extension method in c# that is an improvement of the extensionmethod string[] getBetweenAll(string source, string startstring, string endstring); Originally this extensionmethod found all substrings between two strings, for example: string source = "<1><2><3><4>"; source.getBetweenAll("<", ">"); //output: string[] {"1", "2", "3", "4"} But if you had another occurrence of < in the beginning it would just get between that and the whole string string source = "<<1><2><3><4>"; source.getBetweenAll("<", ">"); //output: string[] {"<1><2><3><4"} So I re-wrote it to be more exact

I need to input a two strings, with the first one being any word and the second string being a part of the previous string and i need to output the number of times string number two occurs. So for instance:String 1 = CATSATONTHEMAT String 2 = AT. Output would be 3 because AT occurs three times in CATSATONTHEMAT. Here is my code: public static void main(String[] args) { Scanner sc = new Scanner(System.in); String word8 = sc.next(); String word9 = sc.next(); int occurences = word8.indexOf(word9); System.out.println(occurences); } It outputs 1 when I use this code. You could also try: public
