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 code to this question can be de4fined as follows:
double power;
power = Math.pow(base, exp);
Explanation:
In the given question the choices were missing, that's why we defined the correct code only.
- In the given code a two double variable "base and exp" is declared, that input the value from the user-side, and store its value into there respective variables.
- In the next step, "power", that is a double variable is declared, which uses the "Math.pow" function that calculates given values power and prints its value.
