What is the output of this Java program?

class Driver { public static void main(String[] args) { int[] x = {6,8,9,6,7}; int n = x.length; for(int j = n-1; j > 0; j--) x[ j ] = x[ j-1 ]; for(int j = 2; j < n; j++) System.out.print(x[ j ]); } }

6)

What is the result of executing this code snippet?

int[] marks = { 90, 45, 67 }; for (int i = 0; i <= 3; i++) { System.out.println(marks[i]); } 

Group of answer choices

The code snippet does not give any output.

The code snippet displays all the marks stored in the array without any redundancy.

The code snippet causes a bounds error.

The code snippet executes an infinite loop.

7)

Complete the following code snippet with the correct enhanced for loop so it iterates over the array without using an index variable.

String[] arr = { "abc", "def", "ghi", "jkl" }; ___________________ { System.out.print(str); } 

Group of answer choices

for (String str : arr)

for (str[] : arr)

for (arr[] : str)

for (str : String arr)

8)

Which code snippet calculates the sum of all the even elements in an array values?

Group of answer choices

int sum = 0; for (int i = 0; i < values.length; i++) { if ((values[i] / 2) == 0) { sum++; } } 

 int sum = 0; for (int i = 0; i < values.length; i++) { if ((values[i] / 2) == 0) { sum += values[i]; } } 

 int sum = 0; for (int i = 0; i < values.length; i++) { if ((values[i] % 2) == 0) { sum += values[i]; } } 

 int sum = 0; for (int i = 0; i < values.length; i++) { if ((values[i] % 2) == 0) { sum++; } }

9)

Which one of the following statements is true about passing arrays to a method?

Group of answer choices

Arrays are passed only if size is specified as another argument

By default, arrays are passed by value to a method

By default, arrays are passed by reference to a method

Arrays, when updated in a called method, are not reflected to the calling method

10)

Which statements about array algorithms are true?

I. The array algorithms are building blocks for many programs that process arrays

II. Java contains ready-made array algorithms for every problem situation

III. It is inefficient to make multiple passes through an array if you can do everything in one pass
