❌ A. 1 ✅ B. 2 ❌ C. 3 ❌ D. Compilation error ❌ E. Runtime error ❌ F. None of the above
Explanation: In this code snippet, the processMap method uses the computeIfAbsent method of the Map interface. If the specified key is not already associated with a value (or is mapped to null), this method associates it with the result of the given function. In this case, the key "Two" is already present in the map with the value 2. Therefore, the computeIfAbsent method does not execute the provided function (k -> k.length()), and it returns the current value associated with the key "Two," which is 2. Option A might be tempting, but it is incorrect because the computeIfAbsent method doesn't execute the function when the key is already present in the map. Option B is the correct answer, representing the value associated with the existing key "Two." Options C and D are incorrect as there is no compilation error or runtime exception in this code. The behavior is as expected with the use of the computeIfAbsent method.

Telegram hopes to raise $1bn with a convertible bond private placement
The super secure UAE-based Telegram messenger service, developed by Russian-born software icon Pavel Durov, is looking to raise $1bn through a bond placement to a limited number of investors from Russia, Europe, Asia and the Middle East, the Kommersant daily reported citing unnamed sources on February 18, 2021.The issue reportedly comprises exchange bonds that could be converted into equity in the messaging service that is currently 100% owned by Durov and his brother Nikolai.Kommersant reports that the price of the conversion would be at a 10% discount to a potential IPO should it happen within five years.The minimum bond placement is said to be set at $50mn, but could be lowered to $10mn. Five-year bonds could carry an annual coupon of 7-8%.
Telegram Be The Next Best SPAC
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.
