private static String removeFromString(String old, String frag)
{
int i = old.indexOf(frag);
while (i> -1) {
String rest = old.substring(i + frag.length());
System.out.println("rest = " + rest);
old = old.substring(0, i);
System.out.println("rest = " + old);
old = old + rest;
System.out.println("rest = " + old);
i = old.indexOf(frag);
System.out.println("i = "+ i);
}
return old;
}
Here the index of first occurrence is obtained outside the “while loop” and if this loop runs until index value is >-1. It extracts the rest of the characters other than “frag” from the index and all the characters for which the given set of characters are removed.

Answer: A. Usability testing
Explanation:
Usability testing would be the correct answer because if the user interface isn't "frendly" then people won't be able to use it properly. Or if you are refering to the word friendly as looking safe, then even more so would be usability testing. Because if people don't like the fonts and styles of the user interface, they might not use it at all.
