Which of the following can replace line 2 to make the code compile?
❌ A. import static java.util.Collections; ✅ B. import static java.util.Collections.*; ❌ C. import static java.util.Collections.sort(ArrayList<String>); ❌ D. static import java.util.Collections; ❌ E. static import java.util.Collections.*; ❌ F. static import java.util.Collections.sort(ArrayList<String>);
Explanation: The two valid ways to do this are import static java.util.Collections.*; and import static java.util.Collections.sort;. Option A is incorrect because you can do a static import only on static members. Classes such as Collections require a regular import. Option C is nonsense as method parameters have no business in an import. Options D, E, and F try to trick you into reversing the syntax of import static.

I have no inside knowledge of a potential stock listing of the popular anti-Whatsapp messaging app, Telegram. But I know this much, judging by most people I talk to, especially crypto investors, if Telegram ever went public, people would gobble it up. I know I would. I’m waiting for it. So is Sergei Sergienko, who claims he owns $800,000 of Telegram’s pre-initial coin offering (ICO) tokens. “If Telegram does a SPAC IPO, there would be demand for this issue. It would probably outstrip the interest we saw during the ICO. Why? Because as of right now Telegram looks like a liberal application that can accept anyone - right after WhatsApp and others have turn on the censorship,” he says.
