It's D because all of this are TRUE.
Answer:
Option (4) is the correct answer.
Explanation:
In Java programming language ,array collection starts from 0 index location and ends in a size-1 index location. So to access the last elements the user needs to use a[Size-1] statement. so to modify the value of the last location of the array the user needs to use "a[size-1]= element;".
But when the user wants to add some new value to the end of the array list collection then he needs to use the statement--
a.add(element); //where add is a function, element is a value and a is a array list object.
Another option is invalid because--
- Option 1 is not the correct because "a[3]=element;" modify the value of the 3rd element of the array.
- Option 2 gives a compile-time error because add functions bracts are not closed.
- Option 3 gives the error because a[4] gives the location of the 5th element of the array but the above question says that a is defined with 4 elements.
Answer:
The correct answer to the following question will be Option C (The application was not developed to react to changes to the gyroscope).
Explanation:
- Most of the android devices are enabled with the sensors. Gyroscope is one of them, it rotates the screen accordingly.
- When the user launches an application on the tablet he or she turns the tablet but the screen doesn't rotate accordingly because the application or software is not enabled to rotate accordingly with the gyroscope.
- By measuring the rate of turn around one particular axis, the gyroscope maintains its level of effectiveness. When the rotations around an aircraft's roll axis are measured, an actual value is determined until the object stabilizes.
