Question

JAVA:

Suppose you have the following array declaration and initialization:

     int [ ] values;

     values = new int[18];

Suppose there is a static method called sumAll that is sent an integer array. The sumAll method computes and returns the sum of all the integers in the array that it is sent (assuming the array is filled). Choose the best example of calling this method:

Group of answer choices

a) sumAll( values[0], values.length )

b) sumAll( values[0 .. 17] )

c) sumAll( values[18] )

d) sumAll( values )

Answer 1

Dear Student,

The option D is correct.

d) sumAll( values )

during method calling we just pass the array name as an argument.

below i have given an example.

==================================================================

//This is the public class
public class Test
{
    // method for sum of elements in an array
    public static int sumAll(int values[])
    {
        int sum = 0; // initialize sum
        int i;
      
        // Iterate through all elements and add them to sum
        for (i = 0; i < values.length; i++)
            sum += values[i];   
        return sum;
    }
   

    // This is the main method
    public static void main(String[] args)
    {
        int[] values = new int[] {1,2,3,4};
    
     System.out.println("Sum of given array is " + sumAll(values));//this bold highlighted is the method calling
        }
}

==================================================================

Sample Output:

Sum of given array is 10
