The question has the multiple choices below
A) Input validation
B) output correction
C) compiler criticism
D) output validation
The answer is (A) Input validation
Also known as data validation, it is the correct and proper
testing of any input supplied by an application or a user. It prevents wrongly
formed data from entering the system. Applications should be able to check and
validate every input entered into the system since it is hard to detect a
malicious user trying to gain entry into software.
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:
No exception will occur
Explanation:
Given
Unsigned Char
Value = 255
Operation = Decrement
Required
What type of exception occurs?
Let's assume the variable is a.
So, we have that
a = 255
The range of values of an unsigned char a is 0 to 255
So, when a is decremented by 1, the new value of a becomes 254
254 is still within the range of 0 to 255.
Hence, no exception will (or is excepted to) occur
