NEW YORK (TheStreet) -- TheStreet's Jim Cramer said he expects the Federal Reserve to implement an interest rate hike, he's bullish on housing-related stocks, he was wrong about Twitter (TWTR) - Get Twitter, Inc. Report and he doesn't expect much merger and acquisition activity yet among oil-related companies.

As Cramer answered viewers' questions on the floor of the New York Stock Exchange, one wrote in that he agreed with recent comments Cramer made about New York Federal Reserve Bank President Bill Dudley and interest rate hikes.

"Dudley said, 'Hey look, we're going to discuss it,' and when you hear that, what it says is, it's still up in the air," Cramer said. "I think that when overseas settles down, which it will, we can have a rate hike. We're strong in this country."
