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