❌ A. Max Integer: 4 Max Double: 3.3 ❌ B. Max Integer: 2 Max Double: 2.2 ❌ C. Max Integer: 1 Max Double: 1.1 ✅ D. Compilation error ❌ E. Runtime error
Explanation: 1. Method Overloading with Generics: • There are two overloaded findMax methods, one using extends Number and the other using extends Comparable<T>. • findMax(List<T extends Number>): Compares Number values using doubleValue() for comparison. • findMax(List<T extends Comparable<T>>): Compares values using the compareTo method, which is available for all classes implementing Comparable.
2. Type Inference and Ambiguity: • When the findMax method is called with List<Integer> or List<Double>, Java tries to infer which method to use. • Both Integer and Double implement Comparable<T>, so both methods are applicable. • This results in a method ambiguity error because Java cannot decide whether to use doubleValue() or compareTo() to compare the elements.
3. Compilation Error: • The ambiguity occurs because the Comparable interface is implemented by both Integer and Double, which causes the compiler to be unable to choose between the two overloaded methods.

You guessed it – the internet is your friend. A good place to start looking for Telegram channels is Reddit. This is one of the biggest sites on the internet, with millions of communities, including those from Telegram.Then, you can search one of the many dedicated websites for Telegram channel searching. One of them is telegram-group.com. This website has many categories and a really simple user interface. Another great site is telegram channels.me. It has even more channels than the previous one, and an even better user experience.These are just some of the many available websites. You can look them up online if you’re not satisfied with these two. All of these sites list only public channels. If you want to join a private channel, you’ll have to ask one of its members to invite you.
What is Telegram Possible Future Strategies?
Cryptoassets enthusiasts use this application for their trade activities, and they may make donations for this cause.If somehow Telegram do run out of money to sustain themselves they will probably introduce some features that will not hinder the rudimentary principle of Telegram but provide users with enhanced and enriched experience. This could be similar to features where characters can be customized in a game which directly do not affect the in-game strategies but add to the experience.
