2: String s1 = "java"; 3: StringBuilder s2 = new StringBuilder("java"); 4: if (s1 == s2) 5: System.out.print("1"); 6: if (s1.equals(s2)) 7: System.out.print("2");
❌ A. 1 ❌ B. 2 ❌ C. 12 ❌ D. No output is printed. ❌ E. An exception is thrown. ✅ F. The code does not compile
Explanation: The question is trying to distract you into paying attention to logical equality versus object reference equality. It is hoping you will miss the fact that line 4 does not compile. Java does not allow you to compare String and StringBuilder using ==.

Bitcoin mining is the process of adding new transactions to the Bitcoin blockchain. It’s a tough job. People who choose to mine Bitcoin use a process called proof of work, deploying computers in a race to solve mathematical puzzles that verify transactions.To entice miners to keep racing to solve the puzzles and support the overall system, the Bitcoin code rewards miners with new Bitcoins. “This is how new coins are created” and new transactions are added to the blockchain, says Okoro.
Start with a fresh view of investing strategy. The combination of risks and fads this quarter looks to be topping.
