Answer:
Command: Systemoutprintln (b)
Output: 7
Explanation:
To solve this problem, we must take into account the precedence of operation.
The division takes precedence before the addition, so we must divide before we add for b.
So
int b = 4 + 6/2 = 4 + 3 = 7.
So
Command: Systemoutprintln (b)
Output: 7
Answer:
It can only be used in superclasses
Explanation:
In computer language, a reserved word is a word that cannot be used as an identifier, such as the name of a variable, function, or label, it is "reserved from use".
If your method overrides one of its superclass's methods, you can invoke the overridden method through the use of the keyword super, it can also be used to refer to a hidden field.
We can conclude that the correct answer is "It can only be used in superclasses" because, in a subclass’ constructor, we can call the superclass’ constructor with the keyword super instead of the superclass’ (constructor’s) name.
I hope you find this information useful and interesting! Good luck!
Answer:
Option(B) i.e "Merge sort " is the correct answer to the given question .
Explanation:
The merge sort follow the approach of divide and conquer technique .It means firstly it divided the given array into the sub parts that sub parts are sorted in comparing the first value with the adjacent value and perform selection sorting in them it means we swap the value if necessary. This process will continue until all the elements are checked .
- When the sub parts are arranged then we will combine them and getting the new or original array that is in sorted order.
- When we perform the merge sort the extra memory is used which is drawback of merge sort .
- All the other options are not Splitting the array in two parts and perform sorting so these are incorrect option .
Ok so what was the question
