Remove element from a string

Question

How can I create a method called delete(String str,int m) that returns the input string with the mth element removed?

Do you want to remove the element from a string array, if yes then you can use the following code, public static T[] RemoveAt (T[] array, int index) { int count = array.Length - 1; T[] result = new T[count]; if (index > 0) Array.Copy(array, 0, result, 0, index - 1); if (index Array.Copy(array, index + 1, result, index, size - index); return result; } But if you want to remove a string at particular position in a string, you will have to specify the length of that item too(that has to be removed).Else everything else following that item will be removed. http://stackoverflow.com/questions/8963738/remove-single-character-from-a-string

To do this in Java, try this: static String delete(String str,int m) { int len = str.length(); if (m len) return str; if (m == 1 && len == 1) return ""; if (m == 1) return str.substring(1); if (m == len) return str.substring(0, len - 1); return str.substring(0, m - 1) + str.substring(m); }
