### Question:
InsertedMethods { public static boolean startsWith(String str, int len, int hashCode) { if (str.length() < len) return false; return str.substring(0, len).hashCode() == hashCode; }  static boolean startsWith(String str, int len, int hashCode);  }### Answer:
@Test public void testStartsWith() { assertTrue(InsertedMethods.startsWith("ich hasse Menschen", "ich hasse ".length(), "ich hasse ".hashCode())); assertTrue(InsertedMethods.startsWith("ich hasse ", "ich hasse ".length(), "ich hasse ".hashCode())); assertFalse(InsertedMethods.startsWith("cancer", "aids".length(), "aids".hashCode())); }
