Jannette has been experiencing slow performance on her computer. Today she received an error message saying that an update to her antivirus program failed. When she checked the update history, she discovered that the program had not been updated for two weeks. She restarted her computer and noticed that a file she was working on was no longer available. She also noticed that the network connection was sending data, even though she does not have an internet browser or any other user initiated network connection open. What should Jannette do first on her computer?

Answer1: 1

(java)3. the answer is  (c): x[2] = 12; if x is an array with three elements, the first element has index 0. the second index has index 1. the third and final element has index 2.4. the answer is (d) for (int y : x) { system.out.println (y) ; }this is an example of syntax  of a "for-each loop."for each element in the integer array x, use y to indicate the current element to do some code with it.the other choice, (c) for (int x : y) { system.out.println (y) ; }. in a for-each loop, the variable to the right of the colon is the array variable; the one to the left is the control variable.choices (a) and (b) have invalid syntax.5. the answer is (a)  int x = {1, 2, 3, 5, 10}; you need to indicate that it is an array using []. without using [], you are trying to assign an array to an integer. you need to use int[] to indicate integer array.so choice (a) has incorrect syntax.
