public class WaterBottle { private String brand; private boolean empty; public static void main(String[] args) { WaterBottle wb = new WaterBottle(); System.out.print("Empty = " + wb.empty); System.out.print(", Brand = " + wb.brand); } }
❌ A. Line 6 generates a compiler error. ❌ B. Line 7 generates a compiler error. ❌ C. There is no output. ✅ D. Empty = false, Brand = null ❌ E. Empty = false, Brand = ❌ F. Empty = null, Brand = null
Explanation: Boolean fields initialize to false and references initialize to null, so empty is false and brand is null. Brand = null is output.

Telegram has no known backdoors and, even though it is come in for criticism for using proprietary encryption methods instead of open-source ones, those have yet to be compromised. While no messaging app can guarantee a 100% impermeable defense against determined attackers, Telegram is vulnerabilities are few and either theoretical or based on spoof files fooling users into actively enabling an attack.
How To Find Channels On Telegram?
There are multiple ways you can search for Telegram channels. One of the methods is really logical and you should all know it by now. We’re talking about using Telegram’s native search option. Make sure to download Telegram from the official website or update it to the latest version, using this link. Once you’ve installed Telegram, you can simply open the app and use the search bar. Tap on the magnifier icon and search for a channel that might interest you (e.g. Marvel comics). Even though this is the easiest method for searching Telegram channels, it isn’t the best one. This method is limited because it shows you only a couple of results per search.
