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 ==.

That said, PayPal has announced that it will enable cryptocurrency as a funding source for purchases this year, financing purchases by automatically converting crypto holdings to fiat currency for users. “They have 346 million users and they’re connected to 26 million merchants,” says Spencer Montgomery, founder of Uinta Crypto Consulting. “It’s huge.”
Tata Power whose core business is to generate, transmit and distribute electricity has made no money to investors in the last one decade.
