Explanation / Answer
Below is your code. I hope this is what you wanted....

*/
public class FlyweightTest {
@Test
public void testObjectEquivalency() {
// Create 3 SharedFlyweight instances.
Flyweight sharedflyweight1 = FlyweightFactory.getFlyweight("key1", "value1");
Flyweight sharedflyweight2 = FlyweightFactory.getFlyweight("key2", "value2");
Flyweight sharedflyweight3 = FlyweightFactory.getFlyweight("key1", "value3");
// 3 shared flyweight object equivalency tests
assertNotEquals(sharedflyweight1, sharedflyweight2);
assertEquals(sharedflyweight1, sharedflyweight3);
assertNotEquals(sharedflyweight2, sharedflyweight3);
}
@Test
public void testNonObjectEquivalency() {
// Create 3 UnSharedFlyweight instances.

"value3");

assertNotEquals(unsharedFlyweight1, unsharedFlyweight3);
assertNotEquals(unsharedFlyweight2, unsharedFlyweight3);
}
