1: public class _C { 2: private static int $; 3: public static void main(String[] main) { 4: String a_b; 5: System.out.print($); 6: System.out.print(a_b); 7: } }
❌ A. Compiler error on line 1. ❌ B. Compiler error on line 2. ❌ C. Compiler error on line 4. ❌ D. Compiler error on line 5. ✅ E. Compiler error on line 6. ❌ F. 0null ❌ G. nullnull
Explanation: Option E is correct because local variables require assignment before referencing them. Option D is incorrect because class and instance variables have default values and allow referencing. a_b defaults to a null value. Options A, B, and C are incorrect because identifiers may begin with a letter, underscore, or dollar sign. Options F and G are incorrect because the code does not compile. If a_b was an instance variable, the code would compile and output 0null

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.”
