Which code can be inserted to have the code print 2?
public class BirdSeed { private int numberBags; boolean call; public BirdSeed() { // LINE 1 call = false; // LINE 2 } public BirdSeed(int numberBags) { this.numberBags = numberBags; } public static void main(String[] args) { BirdSeed seed = new BirdSeed(); System.out.println(seed.numberBags); } }
❌ A. Replace line 1 with BirdSeed(2); ❌ B. Replace line 2 with BirdSeed(2); ❌ C. Replace line 1 with new BirdSeed(2); ❌ D. Replace line 2 with new BirdSeed(2); ✅ E. Replace line 1 with this(2); ❌ F. Replace line 2 with this(2);
Explanation: Options A and B will not compile because constructors cannot be called without new. Options C and D will compile but will create a new object rather than setting the fields in this one. Option F will not compile because this() must be the first line of a constructor. Option E is correct.

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.
