return str1.substring(0, s) + str1.substring(s + string2Length);
String[]substrings(String[] arr, int start, int end)
Return specified substrings for all the members of the given array. 
String[] subs = new String[arr.length];
for (int i = 0; i < arr.length; ++i) {
    subs[i] = safeSubstr(arr[i], start, end);
return subs;
