### Question:
Util { public static String toString(int tag) { char[] ba = new char[4]; for (int i = 0; i < 4; i++) { ba[i] = (char) (tag >> ((3 - i) * 8) & 0xff); } return new String(ba); }  static void assertEquals(String expected, String actual); static String toString(int tag); static int fromString(String s); static String pidToString(byte[] libraryPersistentId); static String toUrl(String p); static boolean isIdentifier(String id);  }### Answer:
@Test public void testToString() throws UnsupportedEncodingException { int hdfmInt = 1751410285; assertEquals("hdfm", Util.toString(hdfmInt)); }
