3: boolean x = true, z = true; 4: int y = 20; 5: x = (y != 10) ^ (z=false); 6: System.out.println(x+", "+y+", "+z);
❌ A. true, 10, true ✅ B. true, 20, false ❌ C. false, 20, true ❌ D. false, 20, false ❌ E. false, 20, true ❌ F. The code will not compile because of line 5
Explanation: This example is tricky because of the second assignment operator embedded in line 5. The expression (z=false) assigns the value false to z and returns false for the entire expression. Since y does not equal 10, the left-hand side returns true; therefore, the exclusive or (^) of the entire expression assigned to x is true. The output reflects these assignments, with no change to y, so option B is the only correct answer. The code compiles and runs without issue, so option F is not correct.

Telegram announces Anonymous Admins
The cloud-based messaging platform is also adding Anonymous Group Admins feature. As per Telegram, this feature is being introduced for safer protests.
