❌ 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.

In general, many financial experts support their clients’ desire to buy cryptocurrency, but they don’t recommend it unless clients express interest. “The biggest concern for us is if someone wants to invest in crypto and the investment they choose doesn’t do well, and then all of a sudden they can’t send their kids to college,” says Ian Harvey, a certified financial planner (CFP) in New York City. “Then it wasn’t worth the risk.” The speculative nature of cryptocurrency leads some planners to recommend it for clients’ “side” investments. “Some call it a Vegas account,” says Scott Hammel, a CFP in Dallas. “Let’s keep this away from our real long-term perspective, make sure it doesn’t become too large a portion of your portfolio.” In a very real sense, Bitcoin is like a single stock, and advisors wouldn’t recommend putting a sizable part of your portfolio into any one company. At most, planners suggest putting no more than 1% to 10% into Bitcoin if you’re passionate about it. “If it was one stock, you would never allocate any significant portion of your portfolio to it,” Hammel says.
