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.

Durov said on his Telegram channel today that the two and a half year blockchain and crypto project has been put to sleep. Ironically, after leaving Russia because the government wanted his encryption keys to his social media firm, Durov’s cryptocurrency idea lost steam because of a U.S. court. “The technology we created allowed for an open, free, decentralized exchange of value and ideas. TON had the potential to revolutionize how people store and transfer funds and information,” he wrote on his channel. “Unfortunately, a U.S. court stopped TON from happening.”
What is Telegram Possible Future Strategies?
Cryptoassets enthusiasts use this application for their trade activities, and they may make donations for this cause.If somehow Telegram do run out of money to sustain themselves they will probably introduce some features that will not hinder the rudimentary principle of Telegram but provide users with enhanced and enriched experience.
