Occurrences of substring in a string

Question

Why is the following algorithm not halting for me? (str is the string I am searching in, findStr is the string I am trying to find)

String str = \"helloslkhe         


        

Answer 1

If you need the index of each substring within the original string, you can do something with indexOf like this:

 private static List getAllIndexesOfSubstringInString(String fullString, String substring) {
    int pointIndex = 0;
    List allOccurences = new ArrayList();
    while(fullPdfText.indexOf(substring,pointIndex) >= 0){
       allOccurences.add(fullPdfText.indexOf(substring, pointIndex));
       pointIndex = fullPdfText.indexOf(substring, pointIndex) + substring.length();
    }
    return allOccurences;
}
