Answer:
return values.remove() + values.remove();
Explanation:
The appropriate expression to complete the method, which is designed to return the sum of the two smallest values in the parameter array number is indicated below in bold font :
public static int
sumTwoLowestElements(int[] numbers)
{
PriorityQueue values = new PriorityQueue<>();
for (int num: numbers)
{ values.add(num);
}
return values.remove() + values.remove();
}
The return statementin programming is often used when a function is ready to return a value to its caller.
The correct option is 3.
When an array is passed as a parameter to a function, it is usually passed as a reference parameter. What is actually passed is the address of its first element. Since arrays are typically passed by reference, it means that if the function changes the value of an element in an array, then the corresponding actual array will change that element. To declare an array of real values as parameter one has to specify the parameters.
Answer:
The answer is "option iii" .
Explanation:
In the given question it is defined that a class "Rectangle" is defined in the class a parameter constructor is created that accepts two parameters. In this question, we create an instance of the class. In object creation first, we define class name then object name and use new keyword in the Instance of class and pass parameters.
- In option i), An object name is used first and then class name. It is not correct.
- In option ii), In instance creation of the class, we do not use class keyword that's why it is wrong.
Answer:
True
Explanation:
In this pseudocode the programmer defines 3 variables, x=1, y=2 and z=3, then he creates a conditional that states that if any of the previously defined variables has the value of 1 then a True will be displayed, on the other hand, if none of the variables has the value of 1 then a False will be displayed. In this case x=1, so it will display a True.
