❌ A. LinkedHashMap: {B=5, A=2, C=1, E=3, D=4}; TreeMap: {B=5, D=4, E=3, A=2, C=1} ❌ B. LinkedHashMap: {B=5, A=2, C=1, D=4, E=3}; TreeMap: {B=5, A=2, C=1, D=4, E=3} ❌ C. LinkedHashMap: {A=2, B=5, C=1, D=4, E=3}; TreeMap: {C=1, A=2, E=3, D=4, B=5} ✅ D. LinkedHashMap: {A=2, B=5, C=1, D=4, E=3}; TreeMap: {B=5, D=4, E=3, A=2, C=1} ❌ E. Error ❌ F. None of the above
Explanation: 1. LinkedHashMap Behavior: • LinkedHashMap maintains the insertion order of elements. • Here, linkedHashMap will display entries in the exact order they were inserted: {A=2, B=5, C=1, D=4, E=3}.
2. TreeMap with Custom Comparator: • TreeMap typically orders entries based on the natural order of keys, but here it uses a custom comparator to sort entries in descending order based on values from linkedHashMap. • Comparator.comparingInt(linkedHashMap::get).reversed() sorts treeMap by values in descending order, resulting in {B=5, D=4, E=3, A=2, C=1}.
3. Expected Output: • The LinkedHashMap output maintains the insertion order. • The TreeMap output shows entries sorted by values in descending order based on linkedHashMap values.

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.
