❌ A. true true true true ❌ B. false false false false ❌ C. false true false true ✅ D. true true false true ❌ E. false true true true ❌ F. true false false true ❌ G. The code does not compile ❌ H. None of the above
Explanation: On line 15, we have a compile-time constant that automatically gets placed in the string pool as "rat1" . On line 16, we have a more complicated expression that is also a compiletime constant. Therefore, first and second share the same string pool reference. This makes line 18 and 19 print true. On line 17, we have a String constructor. This means we no longer have a compile-time constant, and third does not point to a reference in the string pool. Therefore, line 20 prints false . On line 21, the intern() call looks in the string pool. Java notices that first points to the same String and prints true.

Like a stock, you can buy and hold Bitcoin as an investment. You can even now do so in special retirement accounts called Bitcoin IRAs. No matter where you choose to hold your Bitcoin, people’s philosophies on how to invest it vary: Some buy and hold long term, some buy and aim to sell after a price rally, and others bet on its price decreasing. Bitcoin’s price over time has experienced big price swings, going as low as $5,165 and as high as $28,990 in 2020 alone. “I think in some places, people might be using Bitcoin to pay for things, but the truth is that it’s an asset that looks like it’s going to be increasing in value relatively quickly for some time,” Marquez says. “So why would you sell something that’s going to be worth so much more next year than it is today? The majority of people that hold it are long-term investors.”
