Answer:
1)
officeAC = new AirConditioner();
officeAC.turnOn();
2)
officeAC = new AirConditioner();
officeAC.turnOn();
officeAC.setTemp(69);
Explanation:
1)
In the first statement a new object of the class AirConditioner whose reference is assigned to the officeAC. new is a keyword which creates an object of the class.
Next statement uses the method turnOn(). Reference to the new object officeAC is used to invoke this method turnOn().
2) The first two statements works the same as in 1)
The last statement invokes a method setTemp() using the reference variable and passes the value 69 to this method to set the desired temperature.
Answer:
Stack
Explanation:
Stack is a linear data structure that follows a particular order in the way an operation is done or sequence a job is completed.
It uses either LIFO ( Last In, First Out) which is also known as first come first served sequence or FILO (First In, Last Out) sequence.
There are several real life examples of which we can use the example of replacing the snack items Sarah brought for the customer.
If Sarah used the LIFO method, it means she replaced the snack items first ontop of the already existing snack items that's why there is a mismatch.
Ok we will do it for you cause they are very mean
Answer:
Following are the code:
Code:
total = 0; //assign value to total variable.
for (int i=0; i<x.length; i++) //for loop
{
total=total+x[i]; //add all array elements in total variable.
}
Explanation:
In the following question, it is defined that x and total is variable. Where variable x is an integer type array and total is an integer variable. we define some code for calculating the sum of the array element. In the above code, we use for loop that calculates sum of array elements that can be described as:
- To calculate the sum we use the total variable. In total variable, we assign value 0.
- Then we define for loop in loop we use total variables that add all array (x[]) elements.
