### Question:
RpcCallCache { public String getProgram() { return program; } RpcCallCache(final String program, final int maxEntries); String getProgram(); void callCompleted(InetAddress clientId, int xid, RpcResponse response); CacheEntry checkOrAddToCache(InetAddress clientId, int xid); int size(); @VisibleForTesting Iterator<Entry<ClientRequest, CacheEntry>> iterator();  }### Answer:
@Test public void testRpcCallCacheConstructor(){ RpcCallCache cache = new RpcCallCache("test", 100); assertEquals("test", cache.getProgram()); }
