What is the result of the following code snippet?
3: final char a = 'A', d = 'D';
4: char grade = 'B';
5: switch(grade) {
6: case a:
7: case 'B': System.out.print("great");
8: case 'C': System.out.print("good"); break;
9: case d:
10: case 'F': System.out.print("not good");
11: }


A. great
B. greatgood
C. The code will not compile because of line 3.
D. The code will not compile because of line 6.
E. The code will not compile because of lines 6 and 9

Explanation:
The code compiles and runs without issue, so options C, D, and E are not correct. The value of grade is 'B' and there is a matching case statement that will cause "great" to be printed. There is no break statement after the case, though, so the next case statement will be reached, and "good" will be printed. There is a break after this case statement, though, so the switch statement will end. The correct answer is thus option B.

What is Telegram?

Telegram’s stand out feature is its encryption scheme that keeps messages and media secure in transit. The scheme is known as MTProto and is based on 256-bit AES encryption, RSA encryption, and Diffie-Hellman key exchange. The result of this complicated and technical-sounding jargon? A messaging service that claims to keep your data safe.Why do we say claims? When dealing with security, you always want to leave room for scrutiny, and a few cryptography experts have criticized the system. Overall, any level of encryption is better than none, but a level of discretion should always be observed with any online connected system, even Telegram.

A Telegram spokesman declined to comment on the bond issue or the amount of the debt the company has due. The spokesman said Telegram’s equipment and bandwidth costs are growing because it has consistently posted more than 40% year-to-year growth in users.
