    WeakHashMap empty = new WeakHashMap(0, 0.75f);
    assertNull("Empty hashtable access", empty.get("nothing"));
    empty.put("something", "here");
    assertTrue("cannot get element", empty.get("something") == "here");
    try {
        new WeakHashMap(50, -0.5f);
        fail("IllegalArgumentException expected");
    } catch (IllegalArgumentException e) {
    //expected
    }
    try {

    whm = new WeakHashMap();
    for (int i = 0; i < 100; i++) whm.put(keyArray[i], valueArray[i]);
    whm.clear();
    assertTrue("Cleared map should be empty", whm.isEmpty());
    for (int i = 0; i < 100; i++) assertNull("Cleared map should only return null", whm.get(keyArray[i]));
}
